Optics measuring system

The main optic measuring system consists of a spectroradiometer analyzer and an integrating sphere (2M in diameter). This system is capable of measuring spectral power distribution, chromaticity coordinate, relevant color temperature, dominant wavelength, peak wavelength, color ratio, color purity, color rendering index, luminous flux, luminous efficacy, radiation flux, etc.
