Differential spectrum engine improves overall measurement performance


The optical input of the sensor increases by 50%, the spectral resolution increases by 30%, the signal-to-noise ratio is higher, the repeatability, inter instrument differences, and the data is highly consistent with the standard instrument data. The inter instrument consistency can reach 0.08, and the repeatability can reach 0.005. The relevant technology is protected by Chinese invention patents.

Double optical path design improves repeatability accuracy repeatability accuracy dE*ab≤0.005


The dual optical path design monitors the energy fluctuation of the light source while measuring the sample signal, reduces interference during measurement, obtains higher measurement stability, and improves the measurement repeatability index of the instrument to dE*ab ≤ 0.005. The high standard of measurement speed, accuracy, stability and inter-station difference is guaranteed. The relevant technologies are protected by Chinese invention patents and American invention patents.

Innovative 1nm resolution grating spectroscopy technology


Innovation is the soul of CHNSpec. After nearly 10 years of dedicated research, the grating combined array sensor made by the innovative MEMS process makes the color measurement more accurate on the basis of 1nm spectral resolution, once again leading the industry innovation direction and greatly improving the technical performance of the product. The relevant technologies are protected by Chinese invention patents.


Excellent inter-instrument agreement:dE*ab≤ 0.08,


High repeatability accuracy:dE*ab≤0.005, ensure accurate data transfer between factories

DS-37D Benchtop Spectrophotometer For Color Matching 4

High precision automatic calibration


Advanced automatic calibration technology greatly improves long-term repeatability of instruments. Under constant temperature, the dE*ab of day 1 and day 30 can still reach 0.01. At any temperature change from 0℃ to 40℃, dE*ab can reach less than 0.1.
