Colour Matching Spectrophotometer 400 - 700nm Wavelength Range DS600

Spectrophotometer DS-600 with excellent repeatability accuracy

1. Key technology

(1) Dual optical path design improves repeatability accuracy dE*ab ≤ 0.04

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 ≤ 0.04. 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.

1. Product features

(1)Ultra-high repeatability accuracy: dE*ab ≤ 0.04

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.

The white plate in the calibration base is the basis of the instrument's work. Through long-term investment and research, CHNSpec has integrated the "artificial diamond" zirconium material as the calibration white plate, with a Mohs hardness of 9. As the material itself has the hardness and stability comparable to diamond, the surface of the calibration white plate will not be scratched and will not change colour with changes in temperature and humidity. This is a further improvement in the stability and durability of the calibration whiteboard compared to similar foreign and domestic products that use common industrial ceramics or even plastic as calibration whiteboards, ensuring the performance of the instrument.

(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.

(5)Over 30 measurement parameters and nearly 40 evaluation light sources available

The DS600 series spectrophotometers offer 30+ measurement indicators such as spectral reflectance, CIE-Lab, CIE-LCh, ΔE*ab, opacity, whiteness, yellowness, etc.; and nearly 40 evaluation light sources to choose from such as A, B, C, D50, D55, D65, etc., covering almost all colour measurement indicators and light source types in the industry.

(6) Built-in HD camera for clear observation of the measured area

The DS600 series spectrophotometer can obtain an image of the measured area through the camera when measuring, which can clearly locate the measured area of the sample and avoid inaccurate measurement due to wrong area.
