Abstract

A new mirror mounting technique applicable to the primary mirror in a space telescope is presented. Conventional bipod flexures for mounting mirror bosses are changed to have mechanical shims to adjust gravitational distortions at the mirror surface. Analytical results using finite element methods are compared with experimental results from an optical interferometer. Vibration tests qualified their use in space applications.
