The sun is the intended source of radiation for a solar diffuser for the calibration of spacecraft radiometric sensors. Two unwanted sources have also been identified: (1) solar radiation reflected from the earth and scattered by the atmosphere, and (2) solar radiation reflected from surrounding spacecraft structures. This paper describes the determination of the stray radiation incident on the diffuser for the High Resolution Imaging Spectrometer (HIRIS). Finally, the optimization of the calibration geometry is considered.
