Schafer shall produce mirrors (with and without a RadHard coating) and materials test coupons to deliver to the Government, and subsequently to Raytheon (Tucson) for verification and qualification of fundamental structural properties, radiation effects testing, and optical quality and performance measurements for Exo-atmospheric Kill Vehicle Sensor Telescopes. The mirrors will be Silicon Lightweight Mirror Systems (SLMST) made of pure polycrystalline silicon and Silicon Carbide-SLMST made of pure beta-silicon carbide. The materials test coupons will be C/SiC, a carbon fiber reinforced silicon carbide ceramic matrix composite. Notable, the C/SiC material can serve as the mirror mount and telescope reaction structure for each of our mirrors. Schafer shall also provide the existing materials properties database and test results for these materials to be used in a Raytheon EKV telescope model in order to determine performance issues and suitability of the materials for seeker applications and mission profiles. We shall fabricate 3-inch diameter plano mirrors, polished to a figure of HeNe/10 PV and a surface roughness of 10 Å RMS. A well planned Phase II program will include hardware radiation effects testing by Mission Research Corporation and "Shake, Rattle, Roll" and "Environmental" testing by Zygo Corporation and Raytheon
