Abstract

Spectral irradiance and Radiance Calibrations with Uniform Sources (SIRCUS) is a reference calibration facility that transfers detector based spectral irradiance scales derived from the High Accuracy Cryogenic Radiometer, to broadband filtered detector packages, to transfer-standard spectral irradiance detectors, and to instruments that measure spectral radiance. This facility will be used to realize NIST's illuminance, luminous intensity, radiance temperature, color temperature, and sprectal radiance scales, improving their uncertainties and self-consistency.
