Non-contact Spectral Colorimeter

The Non-contact Spectral Colorimeter is a dual-angle spectrophotometric measurement system designed for measuring material reflectance and color characteristics. The instrument performs measurements under 10° and 45° illumination conditions, enabling accurate evaluation of surface reflectance and color properties. It is widely used in industrial inspection, color quality control, and process monitoring applications.

The measurement system integrates a CIE standard light source with a high-precision spectrometer, forming a single measurement focus on the sample surface through the illumination and detection optical paths. This configuration enables accurate measurement of specular reflectance and color information from material surfaces.
