NMSD Mirror Status ReviewThis presentation provides an overview of the 1.6meter hybrid mirror demonstrator for the Next Generation Space Telescope (NGST) Program. The COI design approach for the NGST program combines the optical performance of glass, with the high specific stiffness capabilities of composite materials. The foundation technologies being exploited in the development of the hybrid mirror focus upon precision composite materials for cryogenic operation, and non-contact optical processing (ion figuring) of the lightweight mirror surface. The NGST Mirror System Demonstrator (NMSD) has been designed and built by Composite Optics, Inc. (COI) and is being optically processed by REOSC The mirror has recently completed the second of three cryogenic optical tests for demonstration of the hybrid technology. The test results will be used for the detailed cryo-figuring of the substrate.
