Paper Abstract

Optical components for space optics--especially coated optical elements which represent the external surfaces of optical space instrumentation--have to work under harsh operation conditions like thermal loads, irradiation by photons, electrons and protons, as well as in atomic oxygen environments at low earth orbits. Additionally they have to withstand other cross contamination coming from the spacecraft. Therefore, the stability against these influences is a decisive factor for the application performance of optical coatings in space- borne devices. Some very recent results, based on the Surface Effects Sample Monitor flight experiment carried out aboard the ORFEUS-Shuttle Pallet Satellite, STS-51, Discovery, are presented here along with laboratory experiments in an UHV-surface analysis system. The topics include ground simulation of selective and complex particle bombardment of optical coatings analyzed by XPS as well as the verification of these results by flight experiments in combination with optical measurements (transmission, scattering).
