Principle
The CR9 + spectrophotometric color difference treasure works based on the Spectrophotometric method, spectra-trophotometry principle. The built-in combined full-light spectrum LED Illuminant (including UV) emits rays of light to illuminate the sample with diffuse illumination (D/8). The reflected light is received in the 8 ° direction, and the light is split through a plane grating to analyze the composite light into monochromatic light. The silicon photodiode array sensor detects the light signal intensity at different wavelengths and converts it into electrical signals. Based on these signals, the internal processor of the instrument calculates the chromatic value, Light spectrum data and Miscellaneous related chroma index of the sample in various Color Spaces.
