DS-700A Spectrophotometer
Ultra-high repeatability accuracy:dE*ab≤0.025
1.Core technology
(1)Double optical path design improves repeatability accuracy dE*ab≤0.025
The double optical path design monitors the energy fluctuation of the light source while measuring the sample signal,reduce interference during measurement,get higher measurement stability,increase the instrument measurement repeatability index to dE*ab≤0.025.It ensures the high standard of instrument, measuring speed, accuracy, stability and consistency of inter-station difference.Relevant technologies are protected by Chinese invention patents and American invention patents.

(2)Innovative concave grating optical path structure
Innovation is the soul of instrument.After nearly 10 years of intensive research, the concave grating is used to achieve better than 10 nm optical separation ability, which greatly improves the technical performance of the product.Relevant technologies are protected by Chinese invention and American invention patents. It has independent intellectual property rights worldwide.

Relevant technologies have won the third prize of Zhejiang Provincial Science and Technology Progress Award and the Excellent Product Award of China Instrument and Meter Society
(2)Excellent inter-stage consistency:dE*ab≤0.25
The excellent technology and process level ensure that the DS700A has excellent consistency between platforms.BCRA series standard color bricks are used for color transfer and color value traceability, which ensures that the same type of instrument still maintains excellent inter-stage difference level between upstream and downstream companies.

(3)The calibration base and zirconium reference with Mohs hardness of 9 are used to calibrate the instrument, which ensures the long-term stability of the instrument
Compared with the existing products, the DS700A spectrophotometer does not need frequent manual calibration when it is used. As long as it is placed on the calibration base, 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 standby.
The white board in the calibration base is the working basis of the instrument. Through long-term investment and research, zirconium material known as "artificial diamond" has been integrated as a calibration whiteboard, and the surface Mohs hardness reaches 9. Because the material itself has the hardness and stability comparable to diamond, it can ensure that the surface of the calibration whiteboard will not be scratched and will not change color with the change of temperature and humidity. Compared with foreign and domestic similar products, ordinary industrial ceramics and even plastics are used as the calibration whiteboard, which further improves the stability and durability and ensures the performance of the instrument.

(4)More than 30 measurement parameters and nearly 40 evaluation light sources are available for selection
DS700A spectrophotometer provides spectral reflectance, CIE-Lab, CIE-LCH, Δ E * ab, covering power, whiteness, yellowness and other 30+measuring indicators; A. B, C, D50, D55, D65 and other nearly 40 evaluation light sources can be selected, covering almost all color measurement indicators and light source types in the industry.
(5)The DS700A supports 4 measurement calibers to choose from
In order to facilitate users to measure samples of different sizes, DS700A spectrophotometer supports 4 calibers for customers to use, stable type: Φ 11mm+ Φ 6mm, smart type: ▽ 11mm+▽ 6mm, which can be flexibly applied to various use and test conditions.
