Our integrating sphere — the HPCS 6500 spectrophotometer — is a critical piece of equipment for LED development. It measures everything we need: luminous flux, color temperature (CCT), color rendering index (CRI), chromaticity coordinates, full spectrum analysis from 380–1050nm, and electrical parameters like power, power factor, and harmonics.
