BEX-8204 RGB color matching experiment apparatus
The color-matching apparatus consists mainly of an integrating sphere, fiber-optic spectrometer, and standard source. Red, green, and blue LEDs or LDs serve as primary sources powered by a custom supply. Varying current changes intensity and continuously varies the R, G, and B tristimulus values to match different colors. Students view changes through the sphere window or use the spectrometer and BSV software to measure color coordinates, color temperature, dominant wavelength, and other colorimetric parameters precisely. An optical power meter measures absolute intensity, helping students understand color-measurement theory and methods.
