Spectroradiometric Detector Measurements: Ultraviolet, Visible, and Near Infrared Detectors for Spectral Power



Thomas C. Larason, Jeanne M. Houston


The National Institute of Standards and Technology supplies calibrated photodiode standards and special tests of photodetectors for spectral radiant power responsivity from 200 nm to 1800 nm. The scale of spectral radiant power responsivity is based solely on detector measurements traceable to the NIST reference absolute cryogenic radiometer maintained by the National Institute of Standards and Technology. Silicon photodiode light trapping detectors are used to transfer the optical power unit from this cryogenic radiometer to monochromator based facilities where routine measurements are performed. A description of current measurement services is given along with the procedures, equipment, and techniques used to perform these calibrations. Detailed estimates and procedures for determining uncertainties of the reported values are also present
