Sensitivity evaluation of mounting optics using elastomer and bipod flexures

A sensitivity evaluation of mounting 100mm optics using elastomer or bipod flexures was completed to determine the relative effects of geometry, structure, material, thermal and vibration environment as they relate to optical distortion. This paper covers both opto-mechanical designs, as well as analytical results from computer modeling and brassboard tests.
