Abstract

A conceptual design and manufacturing program for a lightweight graphite/epoxy steering mirror with a 0.5-2.0-m aperture for use at 10.6 micron is presented. An analysis is performed for the optimization of the mirror natural frequency as a function of component material, structural geometry, and physical dimensions. A 65-m-diameter eggcrate sandwich-core mirror constructed of graphite/epoxy composite material clad on all exposed surfaces with aluminum foil or tin/indium solder is manufactured, and it is indicated that this design can be scaled to larger diameters. Results of a trade study suggest that this type of mirror can be hardened against nuclear X-ray effects given the appropriate choice of cladding materials.
