Over the past several years we have designed and fabricated several variations of a three mirror anistigmat Telescope for a Risk Reduction effort. In order to achieve passive athermalization, use of the same materials for both mirrors and structures is desirable. We fabricated 2 telescopes using investment cast aluminum alloy A356 in the first and investment cast Aluminum/Beryllium alloy 191 in the second, for all components. All optical surfaces and corresponding mounting surfaces are nickel plated and single point diamond tuned. The telescopes were assembled to meet the optical prescription tolerances with no alignment required other than focus. Components and performance levels are totally interchangeable between the telescopes, except for athermalization issues.
