The Sounding of the Atmosphere using Broadband Emission Radiometry (SABER) instrument is a 10-channel earth limb- viewing sensor that is to measure atmospheric emissions in the spectral range of 1.27 micrometer to 16.9 micrometer. Presented in this paper is the stray light design and analysis of SABER. Unwanted radiation from the earth and atmosphere are suppressed by the use of stray light features that are critical to mission success. These include the use of an intermediate field stop, an inner and outer Lyot stop, and super-polished mirrors. The point source normalized irradiance transmission (PSNIT) curve, which characterizes the sensor's off-axis response, was computed using the stray light analysis program APART. An initial calculation of the non-rejected radiance (NRR) due to emissions and scatter from the earth and atmosphere was made using the PSNIT data. The results indicate that stray light will not impede the mission objectives.
