Datasheet: Large Uniform Light Source Systems

Labsphere's Large 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 with the addition of a variable attenuator. The USS-4000 produces zero to 40,000 cd/m² and the USS-6500 produces zero to 34,400 cd/m². Each system monitors luminance levels in both cd/m2 and foot-lamberts and all calibrations are traceable to the National Institute of Standards and Technology (NIST).
