Abstract

This paper will review the suitability of the common four types of reflecting surfaces – Ag, Al, Au and Be - for use aboard satellite borne remote sensing and astrophysical observatories, from the uv to far-ir spectral bands. The choice of appropriate protecting and reflectance enhancing overcoats for these reflecting metals will be discussed. Laboratory test data and optical diagnostic techniques used to verify durability of the selected coatings in a terrestrial storage environment and their sensitivity to a space radiation and cold temperature environment will be presented. For some of the selected coatings, a connection will be made between pre-launch laboratory quality checks and post-launch performance on orbit.
