Colorimeter is an instrument used to measure and compare color differences, mainly for controlling color quality in scientific research and production. The colorimeter simulates the color perception ability of the human eye, uses optical principles to measure the color parameters of the sample, and calculates the difference between the sample and the standard sample. Its core components include light sources, filters, and sensors, which can provide color parameters such as Lab * and quantify color differences through these parameters
