Scientific paper

The contamination control of telescopes with the straylight-rejection capability is reviewed to identify the degradative effects of contaminant phenomena on the measurements. Three levels of optical contamination are discussed including bidirectional reflectance distribution function (BRDF), point-source rejection ratio (PSRR), and nonrejected earth radiance (NRER). Measurements of degradation to low-scatter surfaces are set forth for the Zip telescope during storage and for the Cirris 1A telescope performance. PSRR measurements indicate that the Cirris 1A degraded by a factor of 15 during ground testing. A portable external BRDF station is described that measured cryogenic BRDF and BRDF degradation over the life of the Cirris 1A telescope. The optical contamination measurement described are concluded to be important to both determining the causes of degradation and optimizing telescope performance.
