Abstract

Baffles are placed on the front of telescopes to shade the telescope interior from solar and earth radiation that is outside the instrument's field of view. Benefits and drawbacks of specular baffles, which are being investigated as an alternative to the standard diffuse black baffle, are summarized. An overview of four specular baffles designs, the elliptical baffles, Linlor baffle, bielliptical baffle, and Lockheed-Stavroudis baffle, is given. A stray light analysis of the Lockheed-Stavroudis baffle is reported.
