Double optical path design improves repeatability accuracy
repeatability accuracy dE*ab≤0.01
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≤0.01. 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≤0.15，
High repeatability accuracy：dE*ab≤0.01，
ensure accurate data transfer between factories
Self-developed fluorescence calibration technique
Automatically adjust the UV intensity, and ensure that the instrument value is highly consistent with the reference value when measuring the fluorescent material.
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.
