Total Spectral Radiant/Luminous Flux System LM-ISP
The determination of total spectral radiant flux or its’ photometric counterpart, luminous flux, requires the total output of the source to be measured.
This is typically performed with an integrating sphere input optic which samples all light output from the source. Depending on the size of the source to be measured, Optimum supplies integrating spheres from 35mm to 3M diameter, the former being typically employed for the measurement of the single LEDs and LED lighting.
Fully automated data collection reported out on PDF, text or Microsoft Excel formats.
Fully automated calibration software routines using standard lamps calibrated for directional spectral intensity.
