초록
We present the optomechanical analysis results for a 1-m light-weight mirror system for a space telescope. The mirror has partially-closed pockets at the back surface and three square bosses at the rim for flexure mounting. The mirror design is optimized to satisfy the performance requirements under launch loads and a space environment. Mirror surface distortions due to gravity, assembly,isothermal loads, and moisture absorption are investigated. Mechanical safety issues such as mirror fracture, flexure yielding, and adhesive breakage are also examined.
