Development of a spectral radiance calibration standard in the shortwave infrared (SWIR) range

This paper describes the development of a spectral radiance calibration standard in the shortwave infrared (SWIR) range from 1000 to 2500 nm. Gold-coated and Zenith integrating spheres were developed for the working standard. Calibration of the spectral radiance of the integrating sphere was also investigated. An independent radiometer cross-checked calibration of the spectral radiance of the integrating sphere with a consistency of 1.5%.
