Abstract

This paper describes the process used to verify that the mounts designed for the STIS and COSTAR program would perform as designed. The optics on these two programs were all fabricated to (lambda) /100 rms surface figure. Some of the optics were bonded into mounts and others were mechanically mounted. All the mounts were designed to impart less than 0.005 (lambda) rms additional distortion with a goal of 0.003 (lambda) rms. A series of tests showed that the mounts performed as designed. Stability, thermal performance, contamination, and survivability were also tested.
