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.

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
