Spectrophotometric Color Difference Meter

Measuring geometric conditions: The measuring geometric conditions of a spectrophotometric color difference meter typically follow the 45/0 or d/8 integrating - sphere measurement/observation methods recommended by the CIE (International Commission on Illumination). These conditions ensure the accuracy and comparability of measurement results. Color space and color - difference calculation formula: Spectrophotometric color difference meters use color - space coordinate systems such as Lab or LCH in the CIE color space to represent colors. Meanwhile, they adopt specific color - difference calculation formulas (such as ΔE*ab) to evaluate the color differences between samples and standards.
