Product Description

Spectrophotometer with excellent repeatability accuracy


  (1)Dual optical path design improves repeatability accuracy dE*ab≤0.02

  The dual optical path design monitors light source energy fluctuations while measuring the sample signal, reducing interference during measurement, obtaining higher measurement stability and improving the instrument's measurement repeatability index to dE*ab ≤ 0.02. This ensures the instrument, high standards of measurement speed, accuracy, stability and inter-stage difference consistency. The relevant technology is protected by a Chinese invention patent and a US invention patent.

(2) Innovative 5 micron thick nano-integrated optics

Innovation is the soul of CHNSpec. After nearly 10 years of dedicated research, CHNSpec has adopted nano-integrated optics as the spectroscopic device, which can achieve nano-level spectroscopic capability with only 5 micron thickness of optics, once again leading the direction of innovation in the industry, crossing the technological blockade of foreign products and greatly enhancing the technical performance of the products. The relevant technology is protected by Chinese invention patents.

2. Product features


Repeatability accuracy is an important indicator to describe the accuracy of spectrophotometers. The DS600 series spectrophotometers are evaluated on the basis of a rigorous standard of repeatability, which is unmatched by any other spectrophotometer in its class.

(2)Excellent inter-stage consistency

The superior level of technology and craftsmanship ensures that the DS600 series has excellent inter-instrument agreement. The use of BCRA series standard colour bricks for colour transfer and colour value traceability guarantees an excellent level of inter-stage variation.


(3) Calibration base and zirconium reference with a Mohs hardness of 9 to calibrate the instrument, ensuring long-term stability


       Compared to existing products, the DS600 series spectrophotometer does not require frequent manual calibration when in use. Simply place         it on the calibration base and the instrument will automatically calibrate the overall instrument function and accuracy according to its own               state and environmental factors, ensuring that the instrument is always in a stable state and ready for use.

(4) The DS600 series supports 3 measuring apertures for selection


To facilitate the measurement of samples of different sizes, the DS600 series spectrophotometer supports three apertures for customer use: Φ8mm/Φ11mm+Φ4mm/Φ6mm+3mm, which can be flexibly applied to a variety of different usage and testing conditions.
