In industrial production and daily life, the accuracy of color is becoming increasingly important. Whether it is automobile manufacturing, cosmetic production, or home decoration, the accuracy of color will affect the quality of the product and its market acceptance. To ensure the accuracy of colors, many industries have begun to use colorimeters to detect color differences. This article will introduce how to use a colorimeter to detect whether there is a color difference in the paint color.   I. Working Principle of Colorimeter A colorimeter is an instrument that assesses color differences by measuring the color brightness, saturation and hue of an object's surface. It can convert the color of an object into numerical values, and then calculate these values against the standard color values to obtain the color difference. A colorimeter is usually composed of a light source, a receiver and a processor.   Ii. Steps for Using a Colorimeter 1. Sample preparation     Select representative paint samples and apply them evenly on the cardstock, ensuring the surface of the samples is smooth to avoid deviations when light is reflected on the surface. Place it in a cool place to dry. Avoid sticking and contaminating the instrument, which may affect the measurement results.   2.Measurement stage   Place the colorimeter on the surface of the sample and adjust the Angle so that the light source shines perpendicularly on the sample. Then, press the measurement key, and the colorimeter will automatically measure the color of the sample and obtain the data. Usually, a colorimeter outputs three values: L, A and b. L represents the color brightness, a represents the red-green value, and b represents the yellow-blue value.     3.Data Analysis   Compare the data obtained by the colorimeter with the standard color data to calculate the color difference. Generally speaking, the smaller the color difference value, the closer the color is to the standard color. Commonly used color difference formulas include ΔEab, ΔE00, etc.     4.Result Report   Evaluate the qualification of the sample based on the calculated color difference value. If the color difference value is within an acceptable range, it indicates that the color of the coating meets the requirements. If the color difference value exceeds the acceptable range, the formula of the sample can be adjusted according to the data prompt of the colorimeter, and then a sample that meets the requirements can be obtained. The range value of whether the assessment is qualified or not can be set by the system itself.   Iii. Precautions 1,Keep the instrument clean: The colorimeter needs to be cleaned and maintained both before and after use to extend its service life. 2.Correct operation: Before use, carefully read the user manual and follow the operation steps for measurement. 3.Calibration: Before use, it is necessary to check whether the instrument has been calibrated to ensure the accuracy of the measurement results.

In today's industrial landscape, plastic products are everywhere, ranging from ordinary daily necessities to high-end industrial components. With its rich and diverse properties and wide applicability, plastic has become a crucial material in modern manufacturing. In the plastic industry, haze meters are playing a crucial role and have become a key tool for ensuring product quality. Haze, as one of the important indicators for evaluating the optical properties of transparent or semi-transparent plastic materials, when light passes through the plastic material, due to various factors such as the internal structural characteristics of the material, possible impurities or surface conditions, it will cause light scattering and absorption, thereby making the passing light become hazy and unclear. The haze meter provides a quantitative evaluation basis for the optical performance of products in the plastic industry by precisely measuring the degree of light scattering.   For plastic product manufacturing enterprises, the application of haze meters holds significant implications in multiple aspects. Firstly, it has made significant contributions to ensuring the appearance quality of the product. In application fields with high requirements for appearance, such as optical lenses, display panels, etc., low-haze plastic materials can provide a clear and transparent visual experience, thereby enhancing the product's level and competitive strength. By conducting strict quality inspections with a haze meter, products that fail to meet the haze standards can be detected and eliminated in a timely manner, preventing substandard products from entering the market.   Secondly, the haze meter also plays a crucial role in the process of product development and quality control. When developing new plastic materials or improving production processes, haze meters can provide accurate optical performance data, helping engineers understand the characteristics and changing trends of materials, and thereby optimize formulas and process parameters to enhance the quality stability of products. In the production process, regular sampling and testing of products using haze meters can monitor production quality in real time, adjust production processes in a timely manner, and ensure that products always meet quality standards. Color haze Meter CS-700 (Measuring indicators: color, color difference, haze, transmittance, spectral transmittance) In addition, the haze meter also provides strong support for the standardization construction and quality certification of the plastic industry. Numerous industry standards and quality certification systems have clear regulations on the haze of plastic materials. The measurement results of haze meters can serve as an important reference for determining whether the products meet the standards. By using haze meters for detection, enterprises can make their products more easily recognized by the market, enhancing their credibility and competitiveness.   With the continuous advancement of technology, the performance of haze meters is also constantly upgrading. Modern haze meters feature high precision, high stability and easy operation, which can meet the actual needs of plastic enterprises of different scales. Meanwhile, some advanced haze meters also have data storage, analysis and transmission functions, which can be seamlessly integrated with the quality management system of enterprises, improving the efficiency and informatization level of quality management.   In conclusion, the haze meter holds an irreplaceable position in the plastic industry. It is not only a loyal guardian of product quality, but also an important driving force for the continuous development and progress of the plastic industry. In the future, as the plastic industry's requirements for product quality continue to rise, the application of haze meters will surely become more extensive and in-depth, continuing to contribute strongly to the vigorous development of the plastic industry.

Multispectral technology, with its unique detection and analysis capabilities, has become a key force in achieving breakthroughs and innovations in many fields. This technology decomposes full-band or wide-band optical signals into multiple narrowband beams and images them respectively on corresponding detectors to obtain rich spectral information, allowing us to gain insight into details that are difficult to detect with the naked eye. From the perspective of detection accuracy, a single spectrum is like seeing with a single eye, with limited information, while multispectrum is like having multiple pairs of "eyes" for perception, which can capture light signals in different bands. So, how does multispectral technology realize these magical applications? Let's dig deeper together.   1. Principles and characteristics of multispectral technology In the process of agricultural modernization, multispectral technology is the most widely used in agricultural applications. The camera mounted on the multispectral drone can quickly scan vast farmland and accurately sense key information such as nitrogen content, chlorophyll content and moisture content of crops. Through these data, agricultural experts and practitioners can accurately analyze the growth status of crops, make accurate agricultural decisions based on the analysis results, and achieve precise variable fertilization. This not only reduces the waste of fertilizers and production costs, but also effectively improves the yield and quality of crops. When disaster strikes, multispectral drones can also capture abnormal changes in crops in a timely manner to protect agricultural production. The following is a real picture of the application of Caipu Technology's multispectral camera in the agricultural field. 2.

When disaster strikes, multispectral drones can also capture abnormal changes in crops in a timely manner to protect agricultural production. The following is a real picture of the application of Caipu Technology's multispectral camera in the agricultural field. 3. Application of multispectral technology in the field of security monitoring In the field of security monitoring, multispectral technology has brought a qualitative leap to the monitoring system. Traditional monitoring equipment can often only capture image information within the visible light range, while multispectral monitoring equipment can not only perceive visible light, but also identify infrared and ultraviolet light, thereby obtaining more environmental information. At night or under low-light conditions, multispectral cameras can use infrared light to shoot and clearly present surveillance images; when detecting certain special substances or identifying camouflage, the application of ultraviolet light can play a key role, greatly improving the accuracy and reliability of security monitoring. 4. Potential applications of multispectral technology in the medical field In the medical field, multispectral technology also shows great potential. By performing multispectral imaging analysis on human tissues or diseased areas, doctors can obtain more comprehensive and in-depth physiological and pathological information. Taking skin cancer detection as an example, multispectral imaging technology can help doctors more accurately define the boundaries of lesions and determine the nature of lesions, providing a strong basis for early diagnosis and formulation of treatment plans. It is expected to increase the cure rate of the disease and improve the quality of life of patients. 5. Future Prospects of Multispectral Technology With the continuous advancement of science and technology and the in-depth application of multispectral technology, the application prospects of multispectral will become increasingly broad, promoting the development of various industries in the direction of intelligence and precision. Industry pioneers like Color Spectrum Technology are also constantly researching and applying multispectral technology. Its newly launched multispectral cameras, including FS-500, FS-600and FS-620, all have high resolution, high precision and powerful spectral analysis capabilities, which can accurately detect the growth status of crops and help intelligent and precise agricultural planting. I believe that in the future, multispectral technology will continue to bring more surprises and changes to our lives, making life better.        

Driven by the wave of science and technology, multispectral technology has risen rapidly in many fields, from crop monitoring in precision agriculture, to disease diagnosis in the medical field, and then to quality detection in industrial manufacturing, multispectral technology is playing an irreplaceable role. However, when people want to introduce multispectral devices, the question always arises: Is multispectrum expensive? How to achieve cost-effective procurement? The following is a detailed analysis of these issues.   Is multispectrum expensive?  The price range of multispectral devices is extremely wide, which makes it meaningless to simply answer "expensive" or "not expensive". There is a significant difference in the price of multispectrum, and its price fluctuation is mainly affected by the comprehensive factors such as brand, model, performance and application field. On the market, the basic multispectral camera is mainly for individuals or small enterprises with only initial needs for spectral analysis, and the function is relatively single, and the price is usually around $200. This kind of product can meet some basic teaching experiments, simple spectral observation and other scenarios. At the other end, high-end multispectral equipment applied to professional scientific research institutions and large industrial enterprises, due to its high requirements for performance, accuracy and stability, the price is often as high as $14,000 or more. Like the FigSpec® series multispectral camera of color spectrum, including FS-500, FS-600 and FS-620, its price is different according to the configuration, the product price is usually mainly concentrated in the range of tens of $2,000, which is because the multispectral camera of color spectrum technology has a relatively rich band setting and moderate resolution. It can meet the needs of most agricultural monitoring. For some large agricultural enterprises, although this is a small expense, but considering the precision agriculture management benefits it can bring, such as improving crop yields, reducing the loss of pests and diseases, in the long run, this investment is cost-effective. For some small agricultural cooperatives or individual farmers, such prices may be beyond their reach.                                                                  Factors affecting the price of multispectral products 1,Hardware configuration differences: Different multispectral cameras have differences in resolution, number of bands, sensor types, etc. High-resolution cameras can capture clearer and more detailed images, more bands can obtain richer spectral information, and high-performance sensors can improve the accuracy and stability of data. 2.Performance parameters: the higher the spectral resolution, spatial resolution and radiation resolution, the more clearly the details of the ground objects can be presented, and the technical implementation is difficult and the cost will increase. 3.Market supply and demand relationship: the market supply and demand relationship also has a significant impact on the price of multispectrum products. With the application of multispectral technology in various fields, the market demand for multispectral products is increas-ing. However, due to the professionalism and complexity of multispectral technology, there are relatively few enterprises that can produce high-quality multispectral products, and the market supply is relatively limited. This situation of short supply has pushed up the price of multi-spectrum products to a certain extent. 4. Brand influence: Well-known brands with long-term accumulation of technical advantages, good reputation and perfect after-sales, product prices are generally high. For example, the leading brand in the industry, its product prices are often higher than emerging brand. 5. After-sales service: high-quality after-sales service, including products that provide long-term warranty, rapid technical response and professional training services. As the cost of services invested by enterprises increases, the price will also become higher.   How to choose when buying multi-spectrum? 1. Clear application requirements: Different application fields have different performance requirements for multispectrum. In the field of agriculture, monitoring crop growth, disease and insect pests, it is necessary to focus on the near-infrared and other specific bands of multispectral products that can reflect the characteristics of vegetation, so it is necessary to select the visi-ble and near-infrared bands with high precision multispectral. In security monitoring, it may be necessary to work at night or in low light conditions, then multispectral devices with infrared bands and can image in low light will be more suitable. 2. Reasonable budget planning: Before purchasing multispectrum, make a reasonable budget according to your own economic strength and project funding arrangement. It is necessary to consider not only the procurement cost of the equipment, but also the subsequent mainten-ance, upgrading and purchase costs of supporting equipment. For example, some high-end multispectral machines require regular calibration and maintenance, which also needs to be included in the budget. 3. Brand and reputation: Give priority to brands with good reputation and high reputation in the market. You can learn about product quality and user satisfaction of different brands by consulting user reviews, industry reports and consulting professionals. For example, color spectrum technology provides users with professional technical training to ensure that users can skillfully operate the equipment; At the same time, a perfect after-sales service network has been established, which can respond to the maintenance needs of users in a timely manner and solve the worries of users.   Advantages of multispectrum 1. High resolution: Compared with traditional RGB cameras, multispectrum has rich spectral information and higher resolution. Traditional RGB cameras often can only provide single-dimensional information, while multispectrum with its multidimensional spectral data, with the help of various algorithms and models, the target can be more refined classification and analysis. 2. Data complementarity and fusion: It can be fused with other types of data, such as optical images, radar data, lidar data, etc., to furth-er improve the utilization value and analysis effect of data, and to understand the target object more comprehensively. 3. Information richness: It can capture infrared light, ultraviolet light and other bands of information other than visible light, so that we can see the subtle differences and changes that the human eye cannot detect, such as in agriculture, crops can be detected by near infrared band water stress, and infrared band is used for night monitoring in security. 4. Wide applicability: It has important applications in many fields such as agriculture, environmental monitoring, urban planning, geological exploration and so on. Whether it is macro monitoring of large areas or micro analysis of object details, multi-spectrum can play a role.   The price of multispectrum varies due to a variety og factors, and you need to consider your own needs, budget, and factor such as brand and after-sales service when purchasing , Its strong advantages in various fields have provided strong support for the development of many industries.

Color measurement is mainly divided into the measurement of the color of the light source and the measurement of the color of the object. The object color measurement is divided into fluorescent object measurement and non-fluorescent object measurement. In actual production and daily life, color measurement of non-fluorescent objects is widely used. It is mainly divided into two categories: visual color measurement and instrument color measurement. Among them, instrument color measurement includes photoelectric integration method and spectrophotometry method.   1. Visual method The visual method is the visual perception of light produced by the eyes, the brain, and our life experience. The light we see with the naked eye is generated by electromagnetic waves with a narrow wavelength range, and electromagnetic waves of different wavelengths show different colors The recognition of color is the visual nerve sensation caused by the naked eye after being stimulated by electromagnetic wave radiation energy. The unknown colors of the individual components are added together to describe the resulting unknown colors. Although it is most suitable for color evaluation. The way to rely on it is with the help of the human eye, and it is simple and flexible, but due to the experience of observers and psychological and physiological factors The impact of this method makes the method too many variables and cannot be described quantitatively, which affects the accuracy of the evaluation.   2.The photoelectric integration method For a long time, the density method has occupied a very high position in color measurement, but with the application of CIE1976L *, a *, b * gradually becoming widespread, and has covered the entire work flow from press to printing, people are more and more aware of color The importance of degree, and the rapid development of modern colorimetric have also laid the foundation for the objective evaluation of color by photoelectric integration instruments ( precision color difference meters). The photoelectric integration method is a common method used in instrument color measurement in the 1960s. It does not measure the color stimulus value of a certain wavelength, but measures the tristimulus values X, Y, and Z of the sample through integral measurement over the entire measurement wavelength interval, and then calculates the chromaticity coordinates and other parameters of the sample. When using such three photo detectors to receive light stimuli, the tristimulus values X, Y, and Z of the sample can be measured with one integration. The filter must meet Luther's conditions to accurately match the photo detector. The photoelectric integration instrument cannot accurately measure the tristimulus value and chromaticity coordinates of the excellent source, but can accurately measure the color difference between the two color sources, so it is also called a color difference meter. Foreign color difference meters have been mass-produced since the 1960s, and China has been developing such instruments since the early 1980s. Nowadays, the CS-210 precsision colorimeter produced by Hangzhou CHNSpec Technology Co.,Ltd has been used. CS-210 Precision Colorimeter   3. Spectrophotometry Spectrophotometry is also called spectrophotometer. It compares the light energy reflected (transmitted) by the sample with the standard reflected (transmitted) light energy under the same conditions to obtain the spectral reflectance of the sample at each wavelength, and then uses CIE The provided standard observer and standard light source are calculated according to the following formula to obtain the tristimulus values X, Y, and Z, and then X, Y, and Z are used to calculate the chromaticity coordinates x according to the formulas such as CIE Yxy and CIE Lab. y, CIELAB chromaticity parameters, etc. The spectrophotometer determines the color parameters by detecting the spectral components of the sample. It can not only give the absolute values of X, Y, Z and the color difference value △ E, but also give the spectral reflectance value of the object, and can draw the object. Therefore, it is widely used in color matching and color analysis. The use of such instruments can achieve high-accuracy color measurement, calibration of photoelectric integral color measurement instruments, and establishment of chromaticity standards. Such instruments were first developed in China. CS-600 Integrating Sphere Color Spectrophotometer is color spectrum. Therefore, the spectrophotometer is an authoritative instrument in color measurement.   Color Spectrophotometer CS-600   Company introduction Our CHNSpec Technology Co., Ltd are specialized on manufacturing haze meter, spectrophotometers, colorimeters and gloss meters. Our products have gotten 10 Invention Patents including 1 American Invention Patent, 8 Utility Model Patents, 4 Appearance Patents and 3 Software Copyrights till now.    

Measurement and analysis of haze and clarity guarantee a uniform and consistent product quality and help analyze influencing process parameters and material properties, e.g.cooling rate or compatibility of raw materials.   The figure on the picture shows the measurement principle of the haze meter:   A light beam strikes the specimen and enters an integrating sphere. The sphere's interior surface is coated uniformly with a matte white material to allow diffusion. A detector in the sphere measures total transmittance and transmission haze. A ring sensor mounted at the exit port of the sphere detects narrow angle scattered light ( clarity). Standard Methods The measurement of Total Transmittance and Transmission Haze is described in international standards. Two different test methods are specified: 1. IS013468 Compensation method 2. ASTM D1003 Non-compensation method The compensation method takes the light reflected on the sample surface into account. Differences between the two methods can be approximately 2 Total Transmittance on clear, glossy samples.   ASTM D 1003 Measurement conditions are different during calibration and actual measurement. During calibration, part of the light escapes through the open entrance port of the haze meter. While taking a measurement, the entrance port is covered with the sample, thus, the amount of light in the sphere is increased by the light reflected at the sample surface.     ISO13468 Measurement conditions are kept equal during calibration and measurement due to an additional opening in the sphere. During calibration the sample is placed at the compensation port. For the actual measurement, the sample is changed to the entrance port. Thus, the so-called sphere efficiency is independent of the reflection properties of the sample.     Two Standard Methods in one Unit The clarity and haze meter CS-720 complies with both ASTM and ISO measurement standards. It can meet the following measurement standards ASTM D1003 / D1044, ISO13468 / ISO14782, JIS K7105, JIS K7361, JIS K7163 and other international standards.
