Space Environmental Effects on Coated OpticsSeveral high reflectance mirrors and an output window were selected for the Long Duration Exposure Facility (LDEF) by pre-flight screening using laboratory simulation of natural space radiation. One mirror, a silicon/aluminum oxide design, showed expected excellent stability in orbit and a long shelf life. An aluminum oxide coated calcium fluoride window also showed good stability. Less stable but more interesting behavior was observed in the zinc sulfide based mirrors that showed contamination effects and related dendrite formation. These samples, which were located on both leading and trailing edges, also had interesting impact sites.
