Abstract

Mirrors and their supporting structures, the mirror systems, come in many shapes and sizes. Each system must operate in an environment that imposes unique constraints when combined with the operating system dynamics and other requirements. These constraints make the choice of materials for mirror systems a not so simple task. Many materials are available for use in mirror systems. An overview of the available choices, with emphasis on system compatibility and dimensional stability, is presented. Factors influencing the choice include optical and mechanical requirements, the environment, available fabrication methods and economics. Most available materials are discussed with emphasis on aluminum, beryllium, silicon carbide and silicon carbide/aluminum composites. Properties comparisons are made and fabrication methods discussed. Finally, a methodology for materials selection is presented.
