Abstract

Ball Aerospace is building the Cryogenic Telescope Assembly (CTA) for the Space IR Telescope Facility (SIRTF) project and stray light control is a critical part of this effort. The heliocentric orbit where the Sun is never allowed to illuminate the CTA and the Earth is relatively far away is a key feature for stray light control. Mirror and paint BRDFs were measured at various SIRTF wavelength sin order to provide inputs for the stray light models. Stray light from telescope self emission, a distant point source, and the galaxy were analyzed. The design ensures that stray light will be less than 21 percent of the celestial background at all SIRTF wavelengths.
