Optical components which are being used for space instrumentation have been exposed to space conditions to examine degradation effects. The samples have been mounted into the SESAM (Surface Effects Sample Monitor) instrument which was integrated on the ASTRO-SPAS Satellite. Exposition occurred during the STS-51 mission. It was found out that especially supersmooth glass samples made of BK7 show damage effects which increase the roughness from i.e. 0.05 nm to 0.19 nm.
