Comparison of Two Cryogenic Radiometers at NIST

Abstract

Two cryogenic radiometers from NIST, one from the Optical Technology Division and the other from the Optoelectronics Division, were compared at three visible laser wavelengths. For this comparison each radiometer calibrated two photodiode trap detectors for spectral responsivity. The calibration values for the two trap detectors agreed within the expanded (k=2) uncertainties. This paper describes the measurement and results of this comparison.
