Scientific paper

We describe the design and analysis of a high precision 1-m class fused quartz mirror for cryogenic applications. This design is based on requirements from the 1992 Space Infrared Telescope Facility mission. We present primary mirror derived requirements, comparisons of mirror substrate materials, and mirror geometry trades and analyses. We also address the particular impact on the mirror design due to telescope integration and cryogenic testing in a 1-g environment. We discuss numerous aspects of our proposed mirror design. We also show compliance of this proposed design in meeting the top level optical performance as well as structural and verification requirements in a simple and cost effective manner compared with other geometries.
