Noncontact Spectrocolorimeters 45°光源分光测色仪
The noncontact spectrocolorimeter is a dual-angle spectral instrument for material reflectance and color measurement. Measurements under 10° and 45° illumination obtain both surface reflectance and color information for industrial quality inspection, color consistency control, and process monitoring. CIE standard illumination and a high-precision spectrometer form a single measurement focus where illumination and collection paths meet the sample. Built-in source-stability compensation reduces light-source variation for rapid, stable characterization.
