DS-700A、DS-700D、DS-700E Portable spectrophotometer

DS-700A、DS-700D、DS-700E Portable 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.

2.Product characteristics

(1)Ultra-high repeatability accuracy:dE*ab≤0.025

Repeatability accuracy is an important index to describe the accuracy of spectrophotometer.The excellent optoelectronic test system scheme ensures that the repeatability accuracy of DS700A spectrophotometer reaches a level unmatched by similar productsThe repeatability evaluation standard of DS700A spectrophotometer adopts strict standards, showing excellent repeatability accuracy.

(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
