It is used to measure the chromaticity coordinates, color temperature, color rendering index (R1-R15)), color tolerance, peak wavelength, main wavelength, color purity, half width, color ratio, spectral distribution, luminous flux, light radiation power, ambient temperature, in ball temperature and other parameters of the light source. It meets the requirements of CIE for light and color measurement
