Ultra Lightweight Mirror Fabrication Technology

Abstract

This document discusses the technology for making ultra lightweight, passive, large optics for cryogenic operation in space. The key to the success of this technology is frit bonding. Frit is used with a new approach to fusion welding glass cores. The techniques for surfacing and mounting such a mirror are also developed. The mirror material is investigated to determine whether its homogeneity is adequate for the performance levels required.
