Lastest company cases about How to Choose the Right Colorimeter Based on Material States (Liquid, Powder, Solid)?

How to Choose the Right Colorimeter Based on Material States (Liquid, Powder, Solid)?
In modern industrial manufacturing, color consistency directly determines brand value and quality control. Whether in automotive coatings, plastic masterbatches, fine chemicals, or food processing, the colorimeter / spectrophotometer is an indispensable precision tool in the quality control laboratory.However, many procurement managers frequently face a common dilemma: "Our test materials are highly diverse—some are liquids, some are powders, and others are irregular solids. What kind of colorimeter architecture should we choose to ensure precise and repeatable measurement data?"The physical form of the test material (liquid, powder, solid) directly dictates how light reflects, transmits, and scatters across or through its surface. Choosing the wrong colorimeter or incorrect fixtures leads to severely distorted color data. This comprehensive guide will analyze how to properly select a colorimeter based on your material's state and introduce the solutions provided by CHNSpec Technology. I.Color Measurement for Liquid Materials: The Art of Transmission and Refraction 1.Technical Challenges in Liquid Color MeasurementLiquid materials—such as beverages, edible oils, petrochemicals, pharmaceuticals, and solvents—are fluid, vary in transparency, and allow light to penetrate easily. For fully transparent or translucent liquids, light passes directly through the sample. Standard reflection-based colorimeters cannot capture enough reflected light to generate accurate CIE Lab values. Furthermore, the fluidity and volatility of liquids require instruments with exceptional anti-contamination designs. 2.Core Selection FactorsOptical Geometry: The instrument must support D/0 (Diffuse illumination, 0-degree viewing) transmission measurement mode.Accessory Support: High-quality cuvettes or quartz glass test fixtures are mandatory to maintain a fixed liquid sample thickness.Industry Indices: The device should support liquid-specific color indices such as APHA/Hazen (Pt-Co), Gardner, and Saybolt. 3.CHNSpec Recommended Models: CS-821N / CS-820P Benchtop SpectrophotometersFor liquid measurement, benchtop models provide unparalleled optical stability.CHNSpec CS-821N / CS-820P: These high-end benchtop spectrophotometers feature an integrated architecture supporting both Reflection D/8 and Transmission D/0 geometries. Their spacious transmission chambers (located on the side or top) easily accommodate various specifications of quartz cuvettes. They not only precisely measure CIE Lab color differences but also directly output crucial liquid color indices. II.Color Measurement for Powder Materials: Overcoming Scattering and Texture Challenges1.Technical Challenges in Powder Color MeasurementPowder materials (such as flour, titanium dioxide, pigments, cosmetic powders, and cement) possess surfaces formed by countless microscopic particles. When the light from a colorimeter hits a powder surface, severe multi-angle diffuse scattering occurs. If the compactness of the powder packing varies, or if the grain sizes are uneven, the colorimeter will yield vastly different data even when measuring the exact same sample. 2.Core Selection FactorsMeasurement Aperture: A colorimeter with a Large Aperture is highly recommended. A larger measurement area effectively averages out the surface irregularities of the powder, providing stable and repeatable data.Specialized Test Cell / Powder Press: To ensure a completely flat measurement surface, the powder should be loaded into a dedicated powder test cell or compressed into a stable "color cake" using a powder press.Illumination Structure: A D/8 (diffuse illumination, 8-degree viewing) spectrophotometer is preferred, as it effectively eliminates measurement errors caused by tiny shadows on granular surfaces. 3.CHNSpec Recommended Models: DS-807 Large-Aperture SpectrophotometerCHNSpec DS-807: Engineered specifically for granules and powders, it boasts an ultra-large 50mm measurement aperture. This vast aperture easily handles powder surface inconsistencies, delivering highly repeatable data without requiring overly strict compression techniques. III.Color Measurement for Solid Materials: Adapting to Texture, Shape, and Gloss Variations1.Technical Challenges in Solid Color MeasurementSolid materials represent the widest range of applications and the most complex physical variations:Regular & Flat Solids: Plastic sheets, metal plates, and paper are the easiest to measure directly.Irregular & Small Solids: Plastic pellets, textile yarns, and tiny electronic components.High-Gloss & Textured Solids: Automotive coatings, leather, and 3D-printed parts.Surface gloss and texture heavily distort how the human eye perceives color. Therefore, a colorimeter must be capable of separating SCI (Specular Component Included) and SCE (Specular Component Excluded) data. 2.Core Selection FactorsOptical Geometry: The D/8 (SCI/SCE) structure is the universal standard for solid color checking. SCI mode evaluates the true color formulation (ignoring gloss effects), while SCE mode evaluates the color exactly as the human eye sees it (influenced by gloss). For pure coatings or printed matter, a 45/0 geometry may be chosen to align closely with human visual observation habits.Multi-Aperture Switching: To measure solids of different dimensions, the colorimeter should ideally recognize and switch between various aperture sizes (e.g., 8mm, 4mm, 3mm) automatically.Camera Targeting: For measuring specific micro-zones on solid parts, a built-in camera viewport is essential for perfect alignment. 3.CHNSpec Recommended Models: DS-700D Portable ColorimetersCHNSpec DS-700D: As a flagship model among CHNSpec’s portable spectrophotometers, it supports simultaneous SCI/SCE measurement and delivers exceptional inter-instrument agreement alongside outstanding repeatability. Equipped with an intelligent automatic aperture recognition function, it flexibly caters to diverse color detection needs, ranging from large-area plastic sheets to microscopic solid components. IV.ConclusionBy precisely matching the physical characteristics of materials with the technical parameters of colorimeters, enterprises can effectively minimize common measurement errors. Leveraging its comprehensive product line and numerous patented technologies, CHNSpec Technology provides customers with full-scenario color management solutions covering liquids, powders, and solids. For different material forms, CHNSpec offers tailored colorimeters to help your color quality control seamlessly align with international standards.

Food Packaging & Printing: How to Ensure Brand Color Consistency Using a Colorimeter?
In the fiercely competitive global Fast-Moving Consumer Goods (FMCG) market, food packaging is far more than just a container to protect the product—it is the brand's silent spokesperson. Imagine a consumer standing in front of a supermarket shelf, looking at the same Coca-Cola or Lay's potato chips, only to notice that different batches of the packaging have obvious color variations, such as "red shifting to purple" or "yellow shifting to green." What would they think? For the vast majority of consumers, their first reaction would be: "Is this a counterfeit?" or "Has this product expired?" This is the harsh reality of brand color consistency. For food brands, color deviations in packaging print can directly damage brand trust. However, food packaging materials are extremely complex. From flexible plastic packaging and aluminum foil to paperboard cartons and corrugated boxes, different substrates, ink batches, and printing processes (such as flexography, gravure, and digital printing) all contribute to color variations. How can this pain point be resolved? The answer lies in abandoning naked-eye evaluation in favor of digital color management. And the core tools of this digital management are colorimeters and spectrophotometers. I.The 4 Major Obstacles to Color Control in Food Packaging PrintingBefore jumping into the solution, we must understand why controlling color in food packaging is notoriously difficult: 1.Substrate Diversity: Food packaging utilizes a wide range of materials including laminated films, metallic foils, kraft paper, and plastics. Each material has distinct reflectance, absorption, and base colors. The same ink printed on different substrates will look drastically different to the naked eye. 2.Ink and Coating Variations: Even inks from the same manufacturer can exhibit minor variances between batches. Furthermore, water-based inks commonly used in food packaging are highly sensitive; slight adjustments in viscosity and pH will shift the final color. 3.Complexity of Printing Processes: Factors like the high speed of rotogravure printing, anilox roller wear in flexography, water-ink balance in offset printing, and the subsequent lamination process all introduce unpredictable color drift. 4.Metamerism & Human Error: Visual inspection is highly subjective. It is easily influenced by ambient lighting, operator fatigue, and the phenomenon of metamerism—where two colors match under one light source (e.g., D65 daylight) but look completely different under another (e.g., store fluorescent light). II.Digital Color Management: Understanding ΔE (Color Difference)To completely eliminate subjective errors, the printing and packaging industry relies on the CIE Lab color space and the ΔE color difference formula: In modern food packaging supply chains, global brands enforce strict tolerances on their print vendors: ΔE < 1.0: Perceptible only to highly trained eyes or instruments. This is the premium standard required by top-tier international brands. 1.0 ≤ ΔE < 2.0: Noticeable to experienced QA inspectors; typically accepted as the commercial passing standard for food packaging. ΔE  ≥  2.0: Easily spotted by average consumers on retail shelves. This represents an unacceptable deviation that often leads to rejected shipments and high financial losses. Without quantitative measurement by precision instruments, press operators cannot make data-driven, real-time adjustments during production runs. III.CHNSPEC Color Solutions for Food Packaging & Recommended Models1. The Production QC & Portable Champion: CHNSPEC DS-700D SpectrophotometerFor quality control teams who need to frequently move between the printing floor, ink-mixing room, and the QA laboratory, the DS-700D is the undisputed king of performance and value. Core Advantages: It boasts an exceptional inter-instrument agreement (ΔE*ab ≤ 0.2) and high repeatability (≤ 0.02). This ensures that data measured on a DS-700D in one facility perfectly aligns with a unit used at another site across the globe. Packaging-Specific Performance: It supports simultaneous SCI (Specular Component Included) and SCE (Specular Component Excluded) measurements. Whether you are measuring highly reflective laminated plastic snack bags or matte cardboard boxes, it accurately captures the true color profile. Smart Connectivity: By connecting seamlessly to mobile apps and PC color management software, data is synced to the cloud in real-time, making it an ideal tool for global food brands to monitor overseas contract manufacturers. 2. The Ink and Dot Control Expert: CHNSPEC EX Series Printing Spectrodensitometer (EX PRO/MAX)If your facility focuses heavily on commercial offset, corrugated box printing, or rotogravure flexible packaging, you need more than just color difference data—为 you need to know ink film thickness and dot behavior. The CHNSPEC EX Series is purpose-built for the printing shop. Core Advantages: Seamlessly integrates high-precision spectrophotometric color measurement with advanced printing densitometry. Essential Print Control Features: It measures critical printing parameters such as Dot Gain (Tonal Value Increase), Trapping, Print Contrast, and Ink Density. Featuring a dual-positioning system (physical alignment + built-in camera viewfinder), operators can effortlessly target and measure tiny color bars on the edge of the packaging. Best Applied To: Paper food boxes, liquid milk cartons, and large corrugated outer shipping cases. ConclusionIn the world of food packaging, color equals sales, and color equals brand safety. Implementing CHNSPEC's high-precision colorimeters and spectrophotometers allows packaging printers to shift from reactive guesswork to proactive, data-driven quality control. Not only does this drastically minimize waste, reduce ink costs, and optimize substrate utilization.

How Plastics & Injection Molding Industry Uses Colorimeters to Control Batch Color Differences?
Introduction: In the plastics and injection molding industry, color consistency is not just an aesthetic parameter—it is a direct reflection of a brand's quality and credibility. When faced with multi-batch production, raw material variations, recycled material blending, and complex part assembly, how do molders achieve precise color control? I.The "Color Difference Nightmare" in Injection Molding During the actual production of plastic parts, batch-to-batch color variation is a common and challenging pain point. The factors driving color fluctuations are multifaceted: 1.Raw Material Fluctuations: Slight base color variations exist in different batches of plastic resins (e.g., PP, ABS, PC). Uneven dispersion or ratio mismatch of color masterbatches and pigments also leads to color shifts. 2.Process Parameter Drifts: Variations in barrel temperature, injection pressure, holding time, and mold temperature during injection molding can trigger thermal degradation or alter micro-surface crystallinity, changing the light reflection and gloss. 3.Use of Recycled Materials: To cut costs or comply with environmental mandates, molders often blend regrind materials. Repeated heating shears the polymers, causing yellowing and significantly complicating mixture control. 4.Surface Texture Effects: Due to differing diffuse reflection paths, the exact same color formula will look distinctly different on a glossy surface compared to a textured (matte/grain) surface to the human eye. II.Establishing a Standardized Color QC Workflow Relying solely on visual evaluation introduces major subjective bias (such as ambient lighting conditions, operator eye fatigue, and physiological differences). Integrating a high-precision spectrophotometer is the only way to achieve scientific, quantitative color management. A standard QC workflow includes: Step 1: Establish Digital StandardsMeasure the physical standard plaque provided by the customer using a spectrophotometer. Store its absolute scientific values—L*(lightness), a*(redness/greenness), b* (yellowness/blueness), and spectral reflectance curves—directly into the instrument. Step 2: Define Realistic Color TolerancesIn the plastics sector, ΔE*ab or the more human-eye-aligned ΔE*00 is typically used as the pass/fail index.High-Precision Assemblies (Automotive Interiors, 3C Electronics): ΔE*ab < 0.5.General Consumer Goods: ΔE*ab < 1.0. Step 3: IQC & FAI (Incoming & First Article Inspection)Perform rapid sampling on incoming masterbatches and raw pellets. Furthermore, the "First Article" produced at the start of each molding run must be checked to ensure process parameters have not drifted. Step 4: IPQC (In-Process Quality Control) Sample finished products periodically during production. Compare measurements against the saved digital standard. If the ΔE approaches the threshold, immediately adjust the molding temperature or feed ratio. III.Recommended CHNSpec Models & Key Applications 1. For Complex, Curved, or Mini Plastic Parts: CHNSpec DS-700D Spectrophotometer Key Strengths: Tool-free Multi-aperture Switching, Smart Auto-Calibration, High-Accuracy Dual-Path CMOS The Challenge: Molded parts often feature complex curves, narrow grooves, ribbing, or tiny clips. A single large aperture can cause light leakage, yielding faulty measurements. The CHNSpec DS-700D Solution: 3 Apertures in One Device: Comes standard with 11mm, 6mm, and a specialized 1mm X 3mm strip aperture for tiny parts. Switch apertures in seconds without any tools. Intelligent Auto-Calibration: Equipped with a premium Zirconia (ZrO₂) white tile calibration base. It self-calibrates automatically on the base, eliminating manual calibration errors and protecting the tile from scratches.

Camera-Aided Positioning: Misalignment near part edges ruins measurement data. The DS-420's built-in camera allows real-time viewing of the exact measurement area on-screen, guaranteeing precise alignment. 3. For Transparent/Translucent Plastics & Films: CHNSpec CS-700 Color Haze Meter Key Strengths: All-in-One Measurement of Color, Haze, and Transmittance The Challenge: For optical parts like light guides, phone cases, light diffusers, and plastic packaging films, managing color is only half the battle. Transmittance (T%) and Haze must also be tightly controlled to ensure optimal optical properties. The CHNSpec CS-700 Solution: Fully compliant with ASTM D1003/D1044, ISO 13468, and other global standards. It delivers color metrics (Lab, Yellowness, Whiteness) alongside haze and light transmission in a single, ultra-fast test.

Hyperspectral Imaging Empowers Intelligent Identification of Trace Beverage Evidence in Forensics
Forensics PrefaceTrace stains of beverages like coffee, juice, and alcohol are ubiquitous at crime scenes, making it extremely difficult to distinguish their types with the naked eye. Traditional detection methods mostly rely on sampling and chemical color-development processing, which can easily damage physical evidence and are detrimental to subsequent review. Nature published a study that constructed a complete analysis solution combining hyperspectral imaging, band selection, and deep learning. This solution conducted non-destructive identification experiments on nine categories of beverage stains, providing a new perspective for criminal investigation trace evidence detection. Integrating this study, CHNSpec discusses the landing value of hyperspectral technology in the forensic field. I. Existing Difficulties in Traditional Physical Evidence Detection1.Visual recognition has significant limitations. Coffee and tea, or whiskey and rum, are visually highly similar, making manual differentiation extremely difficult; 2.Chemical testing destroys the original form of the stains, preventing physical evidence from being repeatedly verified; 3.Ordinary spectrometer equipment can only perform single-point acquisition, rendering the detection of large-area traces time-consuming; 4.Interferences such as paper color differences and stain air-drying/oxidation hamper judgment, leaving a lack of standardized data support. Hyperspectral imaging relies on its advantages of non-contact, full-field acquisition of chemical spectral fingerprints to make up for the above deficiencies, becoming a practical optical tool for trace evidence analysis. II. Core Tasks Undertaken by Hyperspectral Cameras in the ExperimentThis study utilized a 400–1000 nm visible-to-near-infrared hyperspectral imaging device, equipped with 204 continuous spectral bands, to fully collect the 3D spectral data cube (2D spatial coordinates + 1D spectral curve) of various stains. The entire acquisition process is standardized and reproducible. 1.Multi-Scenario Standardized Spectral AcquisitionThe study simulated real crime scene conditions, uniformly controlling temperature, humidity, light source angle, and stain droplet volume to perform imaging on 9 categories of beverages (papaya juice, coffee, pomegranate juice, orange juice, tea, red wine, whiskey, rum, and brandy): Substrates covered white, pink, and brown absorbent paper towels, including both flat and folded forms; Acquisition was conducted at 6 time intervals from 0 to 5 hours to capture spectral changes caused by oxidation and evaporation; A 1.5×1.5 cm reflection-free ROI (Region of Interest) was designated for each stain, eliminating edge interference pixels to ensure data purity. Before shooting, white board reflection calibration and dark current calibration were completed to uniformly convert data into standardized reflectance curves. This eliminated numerical deviations caused by equipment and illumination, allowing horizontal comparisons of spectral differences among different samples. 2.Capturing Invisible Chemical Spectral CharacteristicsEvery imaging pixel generates an exclusive spectral curve, recording reflection values at different wavelengths to unlock chemical differences unrecognizable to the human eye: Red wine and pomegranate juice are rich in anthocyanins, resulting in lower reflection values in the 400–700 nm visible light range; Coffee and tea polyphenols exhibit exclusive absorption characteristics in the blue-green bands; The distinguishing signals for whiskey and rum are concentrated in the 750–900 nm near-infrared range. It is precisely the fine data from hundreds of continuous bands that differentiate two types of beverage stains that look highly identical to the eye. 3.Constructing a Complete Standardized Evidence DatasetThe equipment collected over 120,000 raw spectral samples. After cleaning noise and duplicate pixels, more than 110,000 valid spectral samples were formed, with each sample corresponding to 204-dimensional spectral features, serving as the original data foundation for subsequent band selection and deep learning training. Sufficient, multi-variable spectral samples support the algorithm in learning stable spectral patterns of stains under different substrates and air-drying durations, reducing recognition fluctuations caused by the environment. III. Supporting Algorithm Flow: Dimensionality Reduction + Multi-Model Comparison to Enhance Identification StabilityRaw hyperspectral data has a large number of bands, and redundancy exists between these bands. Direct modeling would increase the computational burden, so the study introduced a two-layer data optimization scheme. 1.ANOVA Band Selection to Retain Effective Discriminative BandsThe ANOVA F-test was employed to calculate the discriminative capacity of each band (inter-class variance / intra-class variance), ranking the 204 bands by their differentiation performance. Through 5-fold cross-validation testing of the recognition performance corresponding to different numbers of bands, 162 highly discriminative bands were ultimately selected for modeling, which reduced the scale of data computation while maintaining recognition performance. 2.Comparative Verification of Four Types of Deep Learning ModelsBased on the selected 162-dimensional spectral data, four mainstream network models—MLP, 1D-CNN, LSTM, and CNN-LSTM hybrid network—were trained with unified hyperparameters. Precision, recall, F1-score, and overall accuracy were uniformly adopted for evaluation: MLP (Multilayer Perceptron) fully connected network: Displayed stable performance in fitting global spectral features, outperforming other models in experimental classification;1D-CNN: Excelled at capturing local spectral variations in adjacent bands; LSTM: Suited for sequential feature learning of continuous spectral bands; CNN-LSTM hybrid structure: Integrated local and sequential features, but due to the influence of data volume, its recognition performance was inferior to single networks. Concurrently, paired t-tests and McNemar's tests verified that the performance differences between models possessed statistical significance, ruling out fluctuation interference caused by random sampling. 3.Spectral Patterns Corroborating the Causes of Identification ConfusionThe misclassification logic of the models can be intuitively seen from the spectral curves: the curves of coffee and tea overlap heavily in the 400–550 nm range, and whiskey and rum show only subtle differences in the near-infrared range. These two pairs of samples are prone to mutual misjudgment, which is consistent with the model's confusion matrix results, proving that spectral data can explain recognition errors and enhance the interpretability of identification results. IV. Core Application Value of Hyperspectral Imaging in Forensic Evidence1.Complete preservation of physical evidence: The entire process requires no reagents and involves no contact with stains. After detection, samples can be preserved for other identifications, conforming to judicial physical evidence specifications; 2.Enhanced investigation efficiency: A single imaging session collects the full spectrum of an entire stain area without the need for point-by-point sampling, making it suitable for rapid on-site screening; 3.Differentiation of visually similar traces: Hundreds of continuous bands capture subtle optical differences in organic matter and pigments, solving visual differentiation dilemmas; 4.Strong environmental adaptability: Experiments verified that the equipment can adapt to stains with different background colors, folds, and air-drying states, with future potential to expand to fabrics, credentials, skin, and other substrates; 5.Digital retention of data: Spectral values can be exported and archived, gradually building a trace spectral library to achieve intelligent sample comparison.

How to Read Colorimeter Data? Understanding Lab and ΔE
In modern manufacturing, "color" is a critical metric that defines product quality and brand integrity. Whether in plastics, coatings, textiles, or printing, a slight color variation can lead to product rejection and significant financial losses. To quantify and manage color precisely, quality control (QC) teams worldwide rely on colorimeters or spectrophotometers. However, when you receive a data sheet showing L*, a*, b*, and ΔE values, do you know how to interpret them? This guide will demystify these color measurements to help you master color inspection. I.What is the CIE L*a*b* Color Space? The most widely used mathematical color model in global industry is the CIE  L*a*b* color space (commonly referred to as the Lab space), established by the International Commission on Illumination (CIE) in 1976. It is a 3D color space defined by three perpendicular axes:   1.L*(Lightness Axis): Represents how light or dark a color is. L*= 100 indicates pure white. L*= 0 indicates pure black. 2.a*Red-Green Axis): Represents the red/green chromaticity. Positive values (+a*) trend toward Red. Negative values (-a*) trend toward Green.   3.b* (Yellow-Blue Axis): Represents the yellow/blue chromaticity. Positive values (+b*) trend toward Yellow. Negative values (-b*) trend toward Blue. II.How to Read Δ(Delta) Values on a Colorimeter? In real-world quality control, we rarely look at absolute L*, a*, b* values in isolation. Instead, we compare a Sample against a target Standard. The differences are represented by the Greek letter Δ (Delta): 1.Interpreting +/- signs for ΔL*, Δa*, and Δb*: Metric Meaning of Positive (+) Value Meaning of Negative (-) Value ΔL* Brighter/Whiter (The sample is lighter than the standard) Darker/Blacker (The sample is darker than the standard) Δa* Redder (More red/less green) Greener (More green/less red) Δb* Yellower (More yellow/less blue) Greener (More green/less red) Practical Example: If your colorimeter shows:  ΔL*= +0.5, Δa* = -1.2, Δb* = +0.8. Interpretation: The sample color is slightly lighter, greener, and yellower than the standard target. III.What is ΔE (Total Color Difference)? ΔE represents the total color difference. It is calculated as the straight-line distance between the sample and the standard in the 3D CIE Lab color space using the Pythagorean theorem: ΔE compresses all deviations in lightness, red/green, and yellow/blue into a single, easy-to-understand number. Global buyers and suppliers typically establish a specific ΔE limit in their contracts as the Pass/Fail threshold.

Research on the Application of Colorimeters in Color Quality Control of Liquid Foods
I. Introduction In the international food trade and consumer market, as the old saying goes, "color, aroma, and taste are all essential," among which "color" ranks first. The color of liquid foods (including clarified liquids, emulsion liquids, and viscous semi-solid sauces) is not only the external manifestation of their intrinsic quality and freshness, but also the primary sensory element affecting consumers' purchasing decisions. For example, the bright orange color of orange juice represents an abundance of vitamins, the pure white color of milk reflects the emulsification stability of fat and protein, and the reddish-brown color of soy sauce directly embodies the maturity of the fermentation process.   However, during the production and storage processes, liquid foods are highly prone to color drift due to thermal processing, oxidation reactions, enzymatic browning, light exposure, and microbial activities. If there is a visible color difference between different batches of products, consumers will often suspect product spoilage or formula instability, thereby causing irreversible damage to brand trust. Traditional methods that rely on human eyes for color comparison suffer from huge subjective errors. Against this backdrop, the application of high-precision, digital colorimeters (spectrophotometers) for quantified quality control has become an important trend for the modern liquid food industry to achieve standardized, globalized, and cross-regional production. II. Core Technical Difficulties and Color Measurement Modes in Liquid Food Color Measurement Unlike solid or powdered foods, liquid foods face diversified challenges in color measurement due to their unique physical and optical characteristics, which are mainly manifested in the following aspects:   1.Transmission Measurement of Transparent Liquids: Such as liquor, clarified fruit juice, edible oil, mineral water, etc. These samples possess light permeability, and their color depends mainly on the absorption characteristics of transmitted light. Measuring this type of liquid must adopt the Transmission Mode. Through a sample cell (cuvette) with a fixed optical path, the light penetrating the liquid enters the optical detector. This type of liquid usually focuses not only on the conventional  L* a* b* color space, but also relies heavily on specific industry color indexes, such as the Platinum-Cobalt index (APHA/Pt-Co) and Gardner index used for edible oils and resins, as well as the Saybolt color scale used for certain petroleum products.   2.Dual-Mode Measurement of Turbid and Emulsion Liquids: Such as milk, yogurt, turbid fruit juice, thick soup, etc. These liquids contain a large amount of protein microparticles, fat globules, or fruit pulp fibers inside, and strong scattering and absorption will occur after light enters. If only the transmission method is used, the light cannot penetrate; if only the reflection method is used, the optical features of the internal medium cannot be captured. Therefore, these foods often require colorimeters that accommodate the Dual Mode of transmission + reflection to comprehensively evaluate their surface color and overall turbidity.   3.Non-Contact and Professional Container Measurement of High-Viscosity Semi-Solid Liquids: Such as flavoring sauces (tomato sauce, salad dressing), honey, oyster sauce, etc. These samples do not flow easily and can very easily adhere to the measurement window, causing contamination of the optical lens, which makes cleaning extremely inconvenient and may even trigger cross-contamination of food. The key to solving this difficulty lies in using colorimeters equipped with specialized testing accessories (such as liquid sample cups of specific specifications), or adopting a non-contact measurement architecture, ensuring both hygienic safety and data accuracy. III. Adaptation Solutions of CHNSpec Colorimeters in Liquid Food Color Management 1.DS-812N Series / CS-810 Benchtop Liquid Spectrophotometric Colorimeter Aiming at high-transparency liquid foods such as mineral water, liquor, edible oil, and clarified syrup, CHNSpec has launched the DS-810N and CS-810 benchtop liquid-specific colorimeters.   Optical Performance: The instruments adopt the D/0 illumination geometry condition, with built-in high-sensitivity, UV-enhanced silicon photodiodes as receivers, significantly upgrading the measurement range of transmittance to 0~200%. This ensures that even when facing liquid samples whose colors are extremely close to transparent with only subtle differences, extremely weak optical fluctuations can still be captured.   Integrated Specialized Color Indexes: They can not only directly output precise L* a* b*and  ΔE*  data, but also perfectly integrate multiple parameters universal in international food and chemical trade, such as the Platinum-Cobalt index (APHA/Pt-Co), Gardner index, yellowness, absorbance, and concentration. By eliminating the subjective randomness of manual visual eye color comparison, they provide fully traceable digital evidence for international trade. 2.CS-821N Series Advanced Benchtop Spectrophotometer Colorimeter For complex turbid, emulsion, or dark liquid foods such as milk, soy milk, thick fruit juice, rice wine, and soy sauce, the CHNSpec CS-821N benchtop spectrophotometer is the ideal choice for the industry.   Dual-Optical Path Spectrum Analysis Technology: The CS-821N adopts a high-intensity pulsed xenon lamp as the light source, cooperating with dual-optical path spectrum analysis technology, which can monitor micro-fluctuations of the light source in real time and perform automatic compensation, guaranteeing extremely high measurement repeatability (the standard deviation of spectral reflectance is within 0.08%).   Full Compatibility of Reflection + Transmission: The instrument supports the D/8 (diffused illumination geometry, 8-degree viewing) reflection mode and D/0 transmission mode, easily mastering color determination from solids and powders to various complex liquids. When measuring milk, its optical architecture can accurately distinguish the faint whiteness and yellowness differences caused by different fat contents (whole fat, low fat, skimmed) or the addition of high-calcium components; when facing soy sauce or petrochemical liquids, it can also provide color data with an extremely high signal-to-noise ratio. IV. Quality Control Process Application of Colorimeters in Liquid Food Production In actual international and local liquid food supply chains, the digital color management of CHNSpec colorimeters runs through three core links:   1.Fine Screening of Raw Materials Entering the Factory: Raw materials entering the factory, such as fruit juice puree, fresh milk, and crude vegetable oil, have base colors that are heavily influenced by origin and season. Using a colorimeter to determine their initial color data can provide a foundation for subsequent formula fine-tuning, preventing color fluctuations of raw materials from causing inconsistency in the final finished product.   2.Optimization of Processing Technology Parameters: In liquid food processes such as ultra-high temperature sterilization (UHT), evaporative concentration, and fermentation (such as soy sauce and beer brewing), excessive heating will lead to the Maillard reaction (browning), thereby deepening the product color. By periodically drawing online samples and measuring them with CHNSpec colorimeters, the heating temperature, pressure, and time can be dynamically adjusted to ensure that the process is maintained in the optimal golden zone.   3.Finished Product Out-of-Factory and Shelf-Life Consistency Assurance: When products are sold to different supermarkets and shelves around the world, a visually uniform color can tremendously establish a high-end, rigorous brand image. Colorimeters can also be used for simulated shelf-life testing, monitoring the impact of light and temperature on the color of food inside liquid packaging, and providing objective quantified data for the improvement of light-shielding and oxygen-barrier properties of packaging materials. V. Conclusion Today, with increasingly strict international food trade access and consumers' more and more demanding requirements for quality, traditional eye color evaluation can no longer meet the needs of the high-end food manufacturing industry in foreign trade. The colorimeter converts abstract, person-dependent visual sensory experiences into universal digital assets of international standards.   The multiple models of precision spectrophotometric colorimeters provided by CHNSpec, including the DS-812N series, CS-810, and CS-821N series, by virtue of their dual-optical path analysis technology, ultra-wide transmission range, and deeply integrated multi-industry specialized color indexes, have constructed a scientific, rigorous, and traceable modern color quality control system for liquid food enterprises. Introducing high-precision colorimeters can not only effectively control the defective rate and save raw materials, but also significantly enhance the core competitiveness of brands in the international market, making every bottle opening a perfect feast of vision and taste.
Lastest company cases about Hyperspectral Imaging Technology for Non-destructive Detection of Tobacco Flue-cured Oil Content

Hyperspectral Imaging Technology for Non-destructive Detection of Tobacco Flue-cured Oil Content
In the leaf quality evaluation system, oil content is one of the important indicators to measure the quality of flue-cured tobacco. Traditionally, oil content evaluation mainly relies on the empirical judgment of professionals, which has problems such as strong subjectivity and relatively low efficiency. In recent years, hyperspectral imaging technology, due to its characteristics of combining graphs and spectra, has demonstrated application potential in the field of agricultural product quality detection. Taking a study on flue-cured tobacco oil content detection as an example, this paper introduces the practical application effect of visible-near-infrared hyperspectral technology in this scenario. Research Background and Experimental DesignThe study selected 634 flue-cured tobacco leaf samples from 22 tobacco-growing provinces (autonomous regions) across the country, covering upper, middle, and lower parts. The research team used the FigSpec series hyperspectral imaging system from CHNSpec (including FigSpec-23 and FigSpec-25 cameras) to synchronously collect the spectral information of tobacco leaves in the wavelength ranges of 400-1000nm and 900-1700nm. During the collection process, by fixing the light source angle and camera distance, illumination uniformity was ensured, and the average value after collecting spectral data twice for each sample was used as the original input. The oil content score was independently evaluated on a 10-point scale by an appearance quality evaluation team consisting of 20 people. The samples were divided into a calibration set (443 samples) and a validation set (191 samples) at a ratio of 7:3. The distribution characteristics of oil content scores in the two sets of samples were consistent with the overall population, providing a reliable foundation for subsequent model construction. Spectral Preprocessing and Correlation AnalysisThe original spectral data contains noise and scattering interference, requiring preprocessing to enhance effective signals. The study compared five single preprocessing methods, including moving average smoothing (MA), multiplicative scatter correction (MSC), standard normal variate (SNV), first derivative (D1), and standardization (SS), as well as their combination strategies. The analysis results showed that MSC and SNV preprocessing could effectively improve the correlation between spectral reflectance and oil content scores. In the wavelength range of 928.36-1177.03nm, the correlation coefficient increased from 0.076-0.124 of the original spectrum to 0.331-0.640. D1 preprocessing, by strengthening the local variation features of the spectral curves, made the number of strongly correlated bands (|r|≥0.4) exceed 100. These results indicate that reasonable preprocessing strategies help to improve the predictive capacity of subsequent models. Model Construction and Performance EvaluationThe study used two algorithms, partial least squares regression (PLSR) and support vector regression (SVR), to construct quantitative prediction models for oil content scores. The PLSR model based on the full visible-near-infrared band had validation set RPD values between 1.642 and 1.775 under most preprocessing conditions, among which the validation set R² reached 0.683 and the RMSE was 0.346 after MA preprocessing. The SVR model had a validation set R² of 0.653 and an RMSE of 0.362 under the D1+SS combination preprocessing. To merge the advantages of both models, the study introduced a weighted average fusion strategy. The fusion model based on the full visible-near-infrared band (PLSR under MA preprocessing and SVR under D1+SS preprocessing) saw its validation set R² increase to 0.721, RMSE drop to 0.324, and RPD reach 1.894, showing a better prediction effect than any single model. Characteristic Band Selection and Model OptimizationHyperspectral data contains hundreds of bands, presenting data redundancy problems. The study adopted the successive projections algorithm (SPA) for characteristic band selection. The results showed that after MA preprocessing, the PLSR model constructed with 95 characteristic bands selected by SPA had a validation set R² of 0.685 and an RMSE of 0.345; after D1+SS preprocessing, the SVR model constructed with 56 characteristic bands selected by SPA had a validation set R² of 0.666 and an RMSE of 0.355. The number of characteristic bands was significantly reduced from 428 in the full band, drastically lowering the data dimensionality. The fusion model of PLSR and SVR based on SPA selection further improved the prediction accuracy, with the validation set R² reaching 0.724, RMSE at 0.323, and RPD at 1.904. This result indicates that characteristic band selection maintains model validity while reducing data redundancy. Application OutlookThis study demonstrates the feasibility of visible-near-infrared hyperspectral technology in the non-destructive detection of flue-cured tobacco oil content. Compared with traditional manual evaluation methods, hyperspectral technology has potential advantages of objectivity, non-destructiveness, and speed, which can provide reference bases for the development of automatic tobacco leaf grading equipment and the construction of intelligent quality control systems. The FigSpec series hyperspectral imaging system from CHNSpec undertook the core data collection task in this study, verifying its applicability in agricultural material quality detection scenarios.
Lastest company cases about Application of Colorimeters in Non-Destructive Testing of Fruits and Vegetables Maturity and Freshness

Application of Colorimeters in Non-Destructive Testing of Fruits and Vegetables Maturity and Freshness
Introduction: The "Visual Economy" and Quality Risk Control in the Global Fruit and Vegetable Supply Chain In modern international food trade and smart agriculture, the "appearance color" of fruits and vegetables is not only the primary visual element to attract consumers, but also a "barometer" of their internal physiological state. From the greenness of immaturity to the redness or yellowness of full ripeness, subtle changes in color directly correspond to the synthesis and decomposition of internal pigments such as chlorophyll, carotenoids, and anthocyanins. Traditional detection of fruit and vegetable maturity and freshness mostly relies on manual visual observation or destructive experiments (such as penetrometer indentation, chemical titration for sugar-acid ratio, etc.). Manual visual observation is highly susceptible to light sources, environment, psychology, and individual physiological differences, leading to high misjudgment rates and an inability to achieve standardization. On the other hand, destructive testing implies high losses and cannot achieve online screening for large-scale, full-volume production lines. With the development of photoelectric detection technology, non-destructive testing (NDT) technology based on colorimeters and spectrophotometers has become a standard configuration for global fruit and vegetable warehousing, cold chain transportation, customs inspection, and deep processing enterprises. I.Data-Driven Color: How Colorimeters "Read" the Maturity and Freshness of Fruits and Vegetables A colorimeter does not simply take a picture, but converts complex color information into unified color space data of the International Commission on Illumination (CIE) (such as CIE L*a*b*, L*C*h*, etc.). Through these high-precision quantitative indicators, supply chain managers can accurately capture subtle physiological changes in fruits and vegetables during harvesting, ripening, and storage. 1. The Color Password of Fruit and Vegetable MaturityDuring the ripening process of fruits and vegetables, the most significant change is shifting "from green to yellow" or "from green to red." The Jump of the a* Value: In the L*a*b* color space, the a* value represents redness-greenness (negative values for green, positive values for red). Taking tomatoes or apples as an example, as maturity increases, chlorophyll degrades, and lycopene or anthocyanins accumulate in large quantities, causing their a* value to quickly turn from negative to positive. By monitoring the critical point of the a* value, harvesters can accurately determine the "Harvest Window." The b* Value and Yellowing: The b* value represents yellowness-blueness (negative values for blue, positive values for yellow). Bananas, citrus, and other fruits show a significant increase in b* value when ripening, reflecting the appearance of carotenoids. 2. Fruit and Vegetable Freshness and Shelf-life PredictionFreshness is often accompanied by water loss, browning, oxidation, and microbial invasion of fruits and vegetables. The Decline of the L* Value (Loss of Gloss and Brightness): L* represents brightness (0 for black, 100 for white). Freshly picked leafy vegetables or berries have high brightness and a wax layer on the surface. As storage and transportation time extends, respiration consumes organic matter and water is lost, leading to a continuous decline in the L* value, resulting in a dim appearance. Browning Index (BI) and Color Difference Variation (ΔE): Cut fruits and vegetables (such as fresh-cut apples, potatoes) or damaged fruits will turn yellow and black quickly under enzymatic browning. By calculating the overall color difference ΔE compared to the standard sample, the colorimeter can capture the early stages of browning that are difficult for the naked eye to detect within one second, thereby achieving advanced warning of shelf-life. II.CHNSpec Fruit and Vegetable Non-Destructive Testing Product Line Aiming at complex application scenarios in the domestic and foreign fruit and vegetable industries, CHNSpec has developed a variety of detection equipment featuring high precision, portability, and high cost-effectiveness to meet a wide range of usage scenarios from fields to professional laboratories. 1. ColorMeter Pro / DS-200 / DS-210 Series: "Pocket Gadgets" for Field Harvesting and Mobile Commercial InspectionIn orchards, greenhouses, or wholesale markets, inspectors need to move frequently, which requires extremely high environmental adaptability. Product Advantages: ColorMeter Pro (Colorimeter) and DS series portable colorimeters are lightweight and extremely easy to operate. Industry Applications: They support multiple measurement apertures (such as 6mm, 11mm), which can perfectly fit the curved surfaces of berries (such as blueberries, grapes) or large drupes (such as peaches, mangoes). Through Bluetooth connection to a mobile APP, quality inspectors can synchronize the measured  L*a*b* data to the cloud database in real time directly at the orchard site, achieving data archiving of origin maturity. 2. DS-700D Handheld Spectrophotometer: Suitable for Quantitative Analysis and Shelf-life PredictionFor large export enterprises or QA (Quality Assurance) departments of supermarket chains, it is necessary not only to look at color differences, but also to have more precise "spectral reflectance" to predict changes in internal chemical components. Product Advantages: DS-700D adopts a D/8 (diffuse illumination, 8° viewing) optical geometry structure, with a repeatability of ΔE*ab≤ 0.025, and a built-in camera for previewing, ensuring that every measurement is accurately focused on the representative area of the fruit. Industry Applications: It can output not only standard color indicators, but also yellowness, whiteness, and reflectance at specific wavelengths, making it suitable for color tracking of kiwifruit, refrigerated apples, and avocados in cold chain transportation. Through long-term accumulated color degradation curves, it directly correlates with fruit firmness and soluble solids content (SSC) to achieve non-destructive shelf-life prediction. 3. CS-820N / CS-821N Benchtop Spectrophotometer: Ideal Choice for Deep Food Processing, Scientific Research, and TeachingIn deep processing industries such as fruit juice, jam, and frozen fruit pieces, the color standardization of raw materials directly determines the brand consistency of the final product. Product Advantages: As a flagship model for laboratory use, CS-820N/821N possesses reliable measurement stability and high-precision color measurement performance. It supports both reflectance measurement (for solid fruit pulp) and transmittance measurement modes (for fruit juice, fruit vinegar, plant extracts). Industry Applications: In post-harvest storage quality control research of kiwifruit, citrus, etc. (such as evaluating the impact of different refrigeration temperatures on fruit quality), CS-820N can accurately establish a baseline color database and has been widely adopted by many agricultural universities and international quality inspection institutions. 4. Featured Extension: Application of Hyperspectral Cameras in Modern Intelligent Fruit Sorting LinesWith the comprehensive upgrade of smart agriculture, traditional single-point color measurement can no longer meet the high-speed sorting needs of several tons per second in large packing houses. The hyperspectral cameras launched by CHNSpec (such as the FS series, covering 400-1000nm) perfectly achieve the "combination of image and spectrum." It can not only capture large-area color features on the surface of fruits, but also utilize the near-infrared band to penetrate the fruit peel, directly online detecting internal sugar content, acidity, latent bruising, and moldy core. This technology has been applied to multiple intelligent fruit sorting lines around the world as one of the key modules for color and internal quality inspection. III.Conclusion: Digital Color, Empowering the Global Green Supply Chain Non-destructive testing is an important direction for the future development of agriculture and the food industry. The introduction of CHNSpec colorimeters and spectrophotometers transforms the rich experience accumulated over a long time by agronomy experts and growers into internationally accepted quantitative color data. If you are looking for effective solutions to improve post-harvest quality control of fruits and vegetables, reduce international trade return rates, and establish a standardized food supply chain, CHNSpec will be a partner worth considering.

Lastest company news about Hyperspectral Pathology Image Segmentation of Cancer Cytoplasm: A New Approach Based on Data Augmentation
Hyperspectral Pathology Image Segmentation of Cancer Cytoplasm: A New Approach Based on Data Augmentation
In pathological diagnosis, Hematoxylin-Eosin (H&E) staining is a commonly used method for observing tissue morphology. Hematoxylin stains cell nuclei blue-purple, while eosin stains cytoplasm and extracellular matrix pink. Pathologists observe these stained sections under a microscope to judge whether cells have undergone cancerous changes. In the process of determining cancer types, accurate identification of the cancer cytoplasm region is a key step. In recent years, hyperspectral imaging technology has gradually entered the field of pathology research. Compared with conventional CMOS cameras, hyperspectral cameras can acquire richer cellular information. However, this technology faces two realistic problems in practical applications. The first problem is the difficulty of data acquisition. The acquisition cost of hyperspectral images is high, and establishing a large-scale annotated dataset is not easy. Yet, deep learning models precisely require a large amount of data to work effectively. The second problem is instrument noise. Hyperspectral cameras based on the linear push-broom mode often generate vertical or horizontal stripe noise, pixel shifts, and other issues during the imaging process. These noises vary according to equipment characteristics and operating environments, making them difficult to avoid completely. To address these problems, a study was published in the journal Informatics in Medicine Unlocked. They proposed a data augmentation method that utilizes CMOS images to generate pseudo-hyperspectral images simulating real instrument noise, which are then used to train a U-Net segmentation model. 1.Why use CMOS images for augmentation?A direct consideration is the annotation cost. The texture of cancer cytoplasm in hyperspectral images is complex, and manually annotating them in grayscale images is both time-consuming and laborious. In contrast, CMOS images are visually clear, and their annotation efficiency is much higher. The research team's idea is: use easily annotated CMOS images to generate pseudo-hyperspectral images with noise, and then use these images to train the model. The specific approach is divided into three steps:The first step is color conversion and brightness adjustment. Convert the CMOS RGB image into a grayscale image, and adjust the brightness through gamma correction and histogram equalization to make it close to the visual effect of hyperspectral images at a specific wavelength band (such as 580 nm). The second step is adding instrument noise. Randomly add vertical and horizontal noise lines to the image to simulate the stripe noise generated in actual hyperspectral cameras due to differences in sensor sensitivity or signal processing. The number of vertical noise lines is between 19 and 29, and the positions and widths of horizontal noise lines are also randomized. In addition, information loss and pixel shifts are simulated. The third step is geometric transformation. Perform operations such as cropping, flipping, and translating on the generated pseudo-images to further expand the dataset. Through this workflow, 44 original CMOS images generated 792 pseudo-hyperspectral images, which, after being merged with 44 original hyperspectral images, brought the training set to 836 images. 2.How was the experimental effect?The research team evaluated model performance using 5-fold cross-validation, employing IoU (Intersection over Union) and Dice coefficient as indicators. When trained with only 44 original hyperspectral images, the IoU was 0.5786 and the Dice coefficient was 0.7304. After adding the pseudo-hyperspectral images, the IoU increased to 0.6458 and the Dice coefficient increased to 0.7820—IoU improved by about 11.6% and the Dice coefficient improved by about 7.1%. The study also found that image brightness and cell density affect the segmentation results. Darker image types and image types with dense cell nuclei showed relatively lower segmentation accuracy. This indicates that the model has a certain dependency on image quality, and also suggests directions for future improvement. 3. What is the significance of this research?For the processing of hyperspectral pathology images, data scarcity and instrument noise are two unavoidable obstacles. This study provides an actionable idea: instead of painstakingly removing noise, it is better to let the model learn to deal with noise during the training stage. Generating pseudo-hyperspectral images with instrument noise from CMOS images not only solves the difficulty of annotation but also enhances the model's robustness against noise. Of course, this study also has limitations. The experimental data came from canine mammary tumor samples, and there were only seven image types. More complex sample types and larger datasets still need to be gradually accumulated. However, from a methodological perspective, this concept of "using easily annotated images to generate noise-containing training samples" provides a valuable practical path for the application of hyperspectral microscopic imaging in pathological diagnosis. With the gradual popularization of hyperspectral imaging equipment in pathology departments, similar data augmentation methods might help researchers train models more efficiently, reducing dependence on large-scale manual annotation.

Lastest company news about What Is a Colorimeter?
What Is a Colorimeter?
In today's global manufacturing industry, where ultimate quality is pursued, color consistency is a direct reflection of brand power. Whether it is automotive paint, plastic products, textiles, or food packaging, a slight color deviation can lead to product returns or damage to brand image. So, what exactly is a colorimeter—the "sharp eye" used to accurately capture and quantify color in industrial production? And how does it work? This article will take you through a comprehensive understanding of this core color measurement tool. 1. What Is a Colorimeter? A colorimeter is a highly precise psychophysical color measurement instrument used to quantify and describe the color of a sample. It mimics the human eye's perception of color but eliminates human subjectivity, fatigue, and environmental lighting variables. By measuring the absorbance and transmittance of specific wavelengths of light, a colorimeter converts visual color into objective, standardized numerical data (such as L*a*b* or L*C*h* color spaces). This allows manufacturers to establish a clear "color standard" and measure the precise deviation (known as ΔE) between a production sample and the target color. 2. How Does a Colorimeter Work?To understand how a colorimeter works, we can look at its internal optical system, which generally consists of three core components: a light source, a set of filters, and a photosensitive detector. The process follows these precise steps: Step 1: Illumination: The instrument’s internal standard light source (usually a long-life LED or Xenon lamp) shines a broad-spectrum light onto the surface of the sample. Step 2: Filtering: The light reflected from or transmitted through the sample passes through a set of specialized tristimulus filters. These filters mimic the sensitivity of the human eye's three types of color receptors (red, green, and blue cones). Step 3: Detection & Calculation: The filtered light hits a high-sensitivity photodetector, which measures the intensity of each primary color wavelength. The internal microprocessor then calculates these signals into international standard tristimulus values (X, Y, Z) and outputs them as readable coordinates like L*a*b*. Through the above formula, the colorimeter instantly tells you if the sample is too red, too blue, too dark, or too light compared to your standard. 3. What Are Colorimeters Used For?Colorimeters are essential quality control (QC) tools utilized across a vast range of industries where color accuracy is critical. Their primary applications include: Quality Control & Inspection: In manufacturing lines (plastics, textiles, paints, coatings), colorimeters are used to check incoming raw materials and inspect finished products to ensure they match the approved master sample. Pass/Fail Assessment: Suppliers use colorimeters to set specific tolerance limits (ΔE < 0.5). If a production batch exceeds this limit, the instrument flags it as a "Fail," preventing defective goods from being shipped. Supply Chain Standardization: For global brands, colorimeters ensure that components manufactured by different suppliers in different countries (e.g., the plastic cap and the glass bottle of a cosmetic product) match perfectly when assembled. Aging and Durability Testing: Companies use them to monitor color degradation or fading over time when products are exposed to UV light, weather, or chemicals. 4. Colorimeter vs. SpectrophotometerWhile both instruments are used to measure color, they differ significantly in complexity, technology, and price. Understanding the differences is crucial for choosing the right tool for your business: A colorimeter is more like a rapid color diagnostic tool. It is compact, fast, and cost-effective, making it ideal for routine color quality inspections and spot checks on factory production lines. A spectrophotometer, on the other hand, is a comprehensive color analysis instrument. It not only provides color difference values but also analyzes the spectral reflectance curve of an object under different light sources. This makes it the ultimate solution for laboratory research and development, computer color matching (CCM), and challenging materials such as highly reflective or textured surfaces. Feature Colorimeter Spectrophotometer Technology Uses tristimulus filters to mimic human eye perception Measures spectral reflectance at each wavelength (nm intervals) Data Output Provides color coordinates (L*a*b*, ΔE) only Provides spectral data, color curves, metamerism analysis, etc Complexity Simple, compact, and highly portable Highly sophisticated with advanced optical geometries Best Used For Routine QC, pass/fail color checking on straight surfaces R&D, complex color matching, formulation, and metamerism analysis Cost Cost-effective and budget-friendly Higher investment, professional-grade 5.

This overcomes the limitations of single-angle measurement to more comprehensively recreate the spatial visual effects of color. 3.Online Automation and Smart Manufacturing Applications: Unlike many traditional brands focused on offline laboratory measurements, CHNSpec targets Industry 4.0 scenarios. Its CRX series of online non-contact color sensors and high-performance hyperspectral cameras can be embedded directly into automated assembly lines to achieve real-time, dynamic color detection, helping enterprises identify defective products at the source. 4.Participation in Industry Standards: As a vital participant in drafting color measurement standards, CHNSpec has been deeply involved in formulating multiple national and industry standards for color science, reflecting its technical expertise and industry influence in the field. 5.Transparent Pricing Strategy: CHNSpec rejects the high-premium model traditional to the color measurement industry. Under identical or superior technical specifications, the procurement cost of CHNSpec equipment is typically one-half to two-thirds that of comparable international brands. Subsequent costs for calibration, maintenance, and software updates are also kept reasonable, ensuring that user investment remains focused on optical technology and long-term service. Traditional Western and Japanese Brands Overview: Stable technology with high brand premiums 1. X-Rite Representative enterprises in the traditional printing, packaging, and textile industries, whose Ci7800 series benchtop spectrophotometers are tightly integrated with the Pantone color system. X-Rite's hardware performance is universally recognized across the industry, but its brand premium is quite pronounced. In recent years, the brand has implemented software subscription models globally (such as Color iMatch) alongside high annual calibration service fees. For enterprises requiring large-scale deployment of color control networks, the hidden costs of long-term maintenance are substantial. 2. Konica Minolta With classic models like the CM-3700A, the brand has accumulated a solid user base in sectors such as plastics and automotive interiors, excelling in data stability and historical compatibility. Konica Minolta follows a "steady and conservative" route, which to some extent has impacted its pace of innovation in smart capabilities and software ecosystems. The price paid by users often corresponds to optical solutions that were finalized years ago. When facing today's agile manufacturing demands—such as mobile connectivity and rapid cloud-based color matching—the system's scalability and flexibility show certain limitations. Furthermore, the after-sales response process is relatively lengthy, and customers must bear substantial costs for imported spare parts and manual maintenance. 3. BYK-Gardner Focusing on comprehensive metrics for coatings and automotive appearance, the brand excels at integrating multi-dimensional appearance parameters—such as color, gloss, orange peel, and distinctness of image (DOI)—into a single instrument. BYK's multi-angle instruments are widely used in the automotive industry, but its pricing is relatively high, and its ecosystem is somewhat closed. BYK deeply binds its hardware with proprietary software. If a factory's core requirement is primarily accurate spectral color measurement, with less demand for other physical appearance indicators, choosing BYK may mean paying an extra premium for "automotive-grade special features" that go unused. 4. HunterLab With early accumulation in the field of color geometry, the brand possesses deep industry expertise in measuring the color of food, beverages, pharmaceuticals, as well as chemical liquids and powders. HunterLab's products lean more toward traditional, closed scientific laboratories. Its benchtop equipment is typically bulky with relatively limited structural flexibility, and the cost of customization for specific industries is high. In modern complex factories that operate at a fast pace and require portable inspections or cross-category measurements, its cross-industry adaptability faces certain limitations. Conclusion: In the global trading environment of 2026, the procurement of color instruments should return to the essentials: advanced technology, excellent repeatability, seamless connectivity, and a reasonable total cost of ownership (TCO) hold greater practical value than brand history.

2026 Latest Hyperspectral Camera Selection and Price Guide
Are you considering purchasing a hyperspectral camera? With the deep integration of industrial automation and laboratory analysis, hyperspectral imaging research has become a highly anticipated focus. Driven by breakthroughs in optical design, intelligent data compression, and edge computing, hyperspectral technology has evolved from an academic tool in ivory towers into a cornerstone of contemporary commercial quality inspection. Current laboratory research achievements are directly empowering future industrial inline solutions. This guide will cover the following content: The underlying working principles of hyperspectral cameras Standard price ranges (Hyperspectral vs. Multispectral) Cost variables: Complete hyperspectral systems vs. standalone hyperspectral cameras Money-saving strategies for hyperspectral imaging systems What is Hyperspectral Imaging? From a physical mechanism perspective, hyperspectral imaging is used to capture and decode photons reflected, transmitted, or scattered from target surfaces. Whether illuminated by natural sunlight or artificial light sources (such as broad-spectrum halogen lamps, xenon lamps, or high-uniformity LEDs), light undergoes precise physicochemical interactions with the internal molecular structures of materials. This interaction leaves a unique "spectral fingerprint" (i.e., the characteristic absorption bands of the material), thereby revealing the exact chemical composition and spatial distribution of the object. By analyzing these dense spectral features, researchers can discover internal defects or compositional heterogeneities undetectable by the naked eye or traditional cameras. The main application fields of CHNSpec hyperspectral systems include: Agriculture: Early detection of crop diseases and chlorophyll mapping Precision Forestry: Early warning of forest pests and diseases, and inversion of canopy leaf area index Geology and Mining: Mineral mapping and core sample classification Advanced Materials: Thin film uniformity and surface coating analysis Security and Anti-counterfeiting: Identification of counterfeit products and detection of foreign contaminants Cultural Heritage: Non-destructive identification of pigment components in cultural relics and spectral analysis for mural restoration Scientific Research Microscopy: Characterization of optical properties of materials at the microscopic scale and composition analysis of biological sections How Do Hyperspectral Cameras Work? Hyperspectral hardware relies on a sophisticated internal architecture—including precision optical components, a dispersive core (gratings or prisms), and high-sensitivity sensor arrays—to split light into dozens or even hundreds of contiguous wavelength channels. 1.Light Capture: Photons reflect from the sample surface, pass through the front lens, and focus onto a tiny entrance slit. 2.Spectral Dispersion: A high-precision diffraction grating or prism disperses the composite light from the same spatial point according to wavelength in a direction perpendicular to the slit. 3.Sensor Projection: This separated light is projected onto a specific detector array, such as a scientific-grade CMOS (sCMOS) or Indium Gallium Arsenide (InGaAs) sensor. 4.Spatial Scanning: To build a complete two-dimensional spatial image, the system requires line-scan push-broom scanning. This can be achieved via external linear translation stages, conveyor belts, or drone aerial surveys. In addition, specific series from CHNSpec already support integrated desktop rail-free scanning, significantly simplifying operational complexity. 5.Data Cube Reconstruction: Dedicated software collects these continuous one-dimensional spectral slices and compiles them into a 3D "hyperspectral cube" (comprising two spatial dimensions and one spectral dimension) using time-space synchronization algorithms to facilitate immediate machine learning or deep learning algorithm classification. Hyperspectral Camera Price Ranges The single largest cost driver in a hyperspectral system is the imaging sensor. The sensor determines the spectral boundaries that the system can target. Silicon-based sensors cover the standard Visible to Near-Infrared (VNIR, 400-1000 nm) spectrum; the technology is highly mature and still offers exceptional cost-performance. Conversely, stepping into the Short-Wave Infrared (SWIR, 900-1700 nm or higher) domain requires specialized InGaAs (Indium Gallium Arsenide) materials or built-in TEC (Thermoelectric Cooling) detectors, which dramatically drives up manufacturing costs. The table below outlines the estimated market benchmark pricing ranges for 2026: Spectral Range Wavelength Sensor Material Est. Price USD Typical Applications VNIR 400 - 1000 nm CMOS $18k – $45k Vegetation Indices, Minor Damage to Fruits and Vegetables, Print Anti-Counterfeiting NIR 900 -1700 nm InGaAs $35k – $75k Grain Moisture/Protein Analysis, Plastic Sorting SWIR 1000 - 2500 nm InGaAs / MCT $50k – $100k Mineral Identification, Quantitative Analysis of Traditional Chinese Medicinal Ingredients, Barcode Penetration Hyperspectral vs. Multispectral Multispectral systems capture discrete, isolated spectral slices—typically between 3 to 20 non-contiguous bands. They feature high frame rates, low data volumes, and significantly lower price tags. If your task is relatively straightforward—such as identifying plant health indices with established mathematical models or sorting obvious plastic types—multispectral imaging is usually entirely sufficient. Hyperspectral systems capture hundreds of narrow bands across a continuous, uninterrupted spectral range. This ultra-high spectral resolution is vital when you need to address subtle chemical differences, analyze complex organic compounds, or build extensive spectral libraries from scratch. During the early R&D phase, hyperspectral cameras are invaluable for precisely locking onto which wavelengths carry the "critical diagnostic information" for a specific application. Once these specific bands are identified, developers can sometimes transition to lower-cost, application-specific customized multispectral cameras for large-scale commercial deployment. Multispectral Camera Pricing Reference category Typical Price Range (USD) describe Entry-Level Multispectral $1,500 – $5,000 Low-resolution, fixed-band cameras (e.g., 5–6 bands); commonly used in educational settings or on DIY drones Industrial / Research Grade $7,500 – $16,000 Features higher precision and spatial resolution, and offers greater customizability; supports up to approximately 20 bands It must be emphasized that while the wavelength range is the core anchor determining price, spatial resolution, spectral resolution, maximum frame rate (line scan speed), as well as the sensor's signal-to-noise ratio (SNR) and cooling method, will all significantly influence the customization cost of your final configuration. Standalone Hyperspectral Camera vs. Complete Hyperspectral Imaging System It is crucial to remember that a standalone camera itself cannot directly collect valid data. A fully operational hyperspectral ecosystem requires several coordinated components working together: Core hyperspectral camera body Dedicated spectral lenses optimized for low distortion and aberration correction Scanning platform (high-precision linear translation stages, industrial conveyor belts, or drone gimbals for aerial surveys) Professional illumination light sources with stable output and continuous spectra (to avoid spectral gaps) Diffuse reflectance calibration white panels with standard radiometric calibration (for reflectance correction) High-performance acquisition and data analysis software High-performance computing workstations When budgeting for a hyperspectral imaging system, you need to consider the integration cost of the entire system—typically, the budget for peripherals and software accounts for 30% to 50% of the total investment. Incorporating Long-Term Research Goals In the past, many push-broom configurations on the market often tied users into proprietary, exclusive, and closed hardware ecosystems. CHNSpec addressed this pain point by focusing on a "modular and open" design philosophy. For instance, our FigSpec series hyperspectral cameras offer outstanding cross-platform adaptability. These instruments adopt standard mechanical interfaces (such as universal threaded holes) and highly compatible data interfaces (such as GigE Vision or USB3.0), allowing them to seamlessly transition from laboratory desktop stands to industrial production line protective enclosures or field tripods without forcing you into expensive, vendor-locked complete system overhauls. Choosing a system compatible with a standard C-mount ensures that your high-precision camera can easily couple optically with standard laboratory microscopes, thereby extending microscopic-scale spectral analysis capabilities at an extremely low cost. Money-Saving Strategies for Hyperspectral Imaging Systems 1.Computer Workstation: Do not pay a premium to order a standard computer from optical manufacturers. Simply request the minimum RAM, graphics card, and processor configuration parameters required by their analysis software, and then purchase the laboratory workstation independently at standard market retail prices. 2.Illumination Light Source: High-quality hyperspectral data requires a continuous emission spectrum. Although proprietary lighting kits are exceptionally expensive, high-stability quartz tungsten halogen (QTH) lamps are ubiquitous among laboratory suppliers and industrial hardware distributors, costing only a fraction of the price. 3.Darkrooms and Laboratory Enclosures: Instead of purchasing expensive custom darkrooms, it is better to build an efficient, light-tight imaging darkbox yourself using matte blackout cloth, high-density foam boards, or custom aluminum profile frames. Ensuring an environment free of stray light interference can significantly enhance the system's signal-to-noise ratio (SNR) without stretching your budget. 4.Lens Selection: On this point, we strongly recommend choosing original brand lenses. Lenses must undergo factory-level radiometric calibration with the specific sensor array to avoid severe distortion. Purchasing multiple calibrated lenses in advance can prevent expensive logistics costs and downtime caused by sending them back to the manufacturer for recalibration later on. A high-performance hyperspectral imaging device will fully empower your future laboratory research. Since each research parameter, spectral resolution requirement, and characteristic band of target materials varies, the actual system cost will depend on your specific technical needs. Please feel free to contact CHNSpec's hyperspectral technology experts at any time to tailor the best configuration solution for your budget.
Lastest company news about Application of Hyperspectral Cameras in the Study of Atomization and Combustion of Boron-Based Nanofluid Fuels
Application of Hyperspectral Cameras in the Study of Atomization and Combustion of Boron-Based Nanofluid Fuels
I. Research Background and Testing Requirements In the field of aerospace propulsion system research, boron-based high-energy nanofluid fuels, as a new type of high-energy-density fuel, have received widespread attention for their atomization and combustion characteristics. In the study of the ignition and combustion characteristics of B/JP-10 nanofluid fuels, the research team needed to test the spatial characteristic emission spectra of the fuel atomization combustion flame. Traditional spectral testing methods struggle to obtain spectral information at different positions of the flame, whereas imaging hyperspectral cameras can simultaneously acquire the spatial and spectral information of the target, meeting the research requirements for spatial distribution analysis of flame components. The research team selected the FS-22 imaging hyperspectral camera produced by CHNSpec Technology Co., Ltd. to systematically test the spatial radiation spectra of the fuel atomization flame. II. Testing Methods and Spectral Selection During the research process, the FS-22 imaging hyperspectral camera was used in conjunction with a nanofluid fuel atomization combustion test system. This test system mainly consists of a sample feeding system, an atomization nozzle, a testing system, and a sampling system. An air atomization nozzle is used to atomize the boron-based nanofluid fuel, and a plasma arc is used to ignite the atomized jet of the sample. The hyperspectral camera was used to collect spatial radiation spectral data of the fuel atomization flame. Based on the typical characteristic spectra of boron element and hydrocarbon fuel combustion, the research team selected two specific radiation bands for analysis: 1. 431 nm (blue band): corresponds to the radiation of CH radicals, used to characterize the combustion reaction of the hydrocarbon fuel JP-10. 2. 581 nm (green band): corresponds to the radiation of BO₂ radicals, used to characterize the combustion reaction of boron particles. Figure 7.11   Radiative Density of 10 wt% B/JP-10 Nanofluid Fuel at 431 nm and 581 nm By performing imaging analysis on the spatial distribution of radiation intensity in these two characteristic bands, researchers can distinguish the dominant reaction types at different positions within the atomized flame. III. Experimental Results and Analysis Spectral Analysis of Axial Center Position Image data acquired by the hyperspectral camera shows that the spectral radiation at the axial center of the atomized torch exhibits obvious variation patterns. The spectral curves at Position 1 and Position 2 contain the characteristic "five-finger peaks" of boron combustion, and the radiation intensity increases with the distance from the nozzle, indicating that a boron combustion reaction exists at the center of the atomized torch from the nozzle to Position 2 and gradually strengthens with the movement of boron particles. From Position 3 to Position 5, the boron characteristic peaks at the center of the atomized flame disappear, indicating that no significant chemical reaction of boron particles occurs in this section. Spectral Analysis of Radial Positions Taking Position 4, where the axial center radiation intensity is highest, as the center, a comparative analysis of spectral radiation at different radial positions revealed: boron radiation characteristic peaks exist at both the upper and lower edges of the atomized torch, but the overall radiation intensity at the upper edge is slightly higher than that at the lower edge. This is because the JP-10 vapor moves upward under the influence of buoyancy, resulting in a larger amount of JP-10 participating in the reaction at the upper part of the torch. Simultaneously, distinct boron radiation characteristic peaks exist at the lower edge, which is consistent with the characteristic of boron moving downward under the influence of gravity. Combustion Zone Division Based on the spatial spectral radiation data acquired by the hyperspectral camera and combined with fuel atomization combustion images, the research team divided the center of the B/JP-10 nanofluid fuel atomization flame along the axial direction of the nozzle into four combustion zones: B/JP-10 coupled combustion zone (outlet section), JP-10 single-phase combustion zone (stable combustion section), B/JP-10 coupled combustion zone (tail flame section), and boron single-phase combustion zone. This regional division provides a basis for further understanding the fuel atomization combustion mechanism. IV. Case Summary The application of the CHNSpec FigSpec FS-22 hyperspectral camera in the research and development of boron-based high-energy nanofluid fuels has achieved the integrated collection of spatial and spectral information during the combustion process, solving the pain point where traditional detection methods struggle to cover the entire flame field and cannot simultaneously obtain component distributions. Its stable imaging performance and fine spectral resolution capabilities provide a reliable detection means for high-energy fuel formula optimization, combustion mechanism research, and combustion model establishment, assisting in technical breakthroughs for new types of aerospace propulsion fuels.
