Abstract
A new generation radiometer-photometer system has been developed in a National Institute of Standards and Technology (NIST) and Gamma Scientific (GS) cooperation to satisfy the increased requirements in the dissemination of NIST responsivity scales. The NIST responsivity scales have been extended from the silicon wavelength range to 2500 nm and in addition to the traditional spectral power responsivity calibrations, spectral irradiance and radiance responsivity calibrations are performed as well. The new generation radiometers and photometers can be utilized to maintain the NIST spectral responsivity scales and also to propagate the extended NIST scales to field applications with a minimal increase in the measurement uncertainty.Citation
