YTR-6304 # Color Matching Experiment

SUMMARY

Color is a psychological perception produced by the objective existence of electromagnetic radiation acting on the human visual organs, involving a variety of disciplines such as physics, biology and psychology. Therefore, people have been committed to the study of color science, from Newton's introduction of the concept of color ring to Young-Helmholtz's theory of the trichromatic to the establishment of the CIE chromaticity system in 1931, which has made great contributions to the further development of chromaticity and provided the basis for the standardization of color measurement. The experimental setup mainly consists of a miniature spectrometer, an integrating sphere, a refrigerated tungsten light source, an LED light source and a power supply. The integrating sphere is covered by a visualization window, which can visually observe the color changes, while the spectrometer and its professional measurement software can accurately measure the color chromaticity coordinates.

FEATURES

• Visual qualitative observation and professional-grade chromaticity measurement

• Industrial-grade spectrometer and light source for both laboratory teaching and scientific experiments
