Datasheet: Medium USS Uniform Light Sources

The Medium Uniform Source Systems are designed to provide exceptional uniform spectral radiance for the test and calibration of imaging and non-imaging detectors. The systems provide stepped luminance output, or continuous output. The USS-1200 produces zero to 40,000 cd/m² and the USS-2000 produces zero to 18,000 cd/m². Each system monitors luminance levels in both cd/m² and footlamberts and all calibrations are traceable to the National Institute of Standards and Technology (NIST).
