Abstract

Contraves Inc. is currently under contract to develop the facility and tooling for processing the Subaru 8.3-meter primary mirror. The optical polishing of an 8-meter class astronomical mirror presents several challenges. Simply the size of the substrate makes all handling and transportation difficult. The mirror substrate is presently being manufactured by Corning Incorporated in Canton, New York. The project includes the transportation from Canton to Wampum, Pennsylvania, the optical processing, and the final delivery to Mauna Kea, Hawaii. This program is based on existing technology. The polishing machine, optical test equipment, and support fixtures are proven equipment. The processes, equipment, and facilities required for the production of the Subaru 8.3-meter monolithic, concave, hyperbolic, thin meniscus mirror are presented here.
