Paper Abstract

Wideband longwave infrared (LWIR) attenuators used in calibration sources can introduce subtle changes in the spectrum of the test beam. As a result, there are probably no sensor calibration sources that have unimpeachable spectral purity at all levels. This paper reviews several of the mechanisms that can alter the spectrum of the test beam, discusses measures that can reduce spectral coloration and describes spectroradiometer configurations that can be used for in situ characterization of the test beam.
