Integrating sphere light sources

Integrating sphere light sources with continuous broadband or LED narrow band emission spectrum. Uniform light sources for use as luminance standards for camera calibration, for the determination of veiling glare, for the adjustment of night vision devices and much more.


Uniform light sources with tungsten-halogen and LED source options.  Integrating sphere diameters from 50mm to 500mm. Monitor detector options. Output control by manual and remote control.
