Mirror segment sensitivity analysis and performance budgets for LUVOIR ULTRA (Conference Presentation)

Paper Abstract

Coronographic missions require ultra-stable mirror systems to achieve 10 E-10 contrast. The LUVOIR ULTRA study is assessing technological capabilities for a 15-meter telescope requiring sub nanometer optical stability. For ULTRA individual mirror stabilities at the picometer level are required. Thermal sensitivities for a proposed mirror design have been incorporated into a stability budget that indicates the level of stability required is attainable. Key factors to meeting stability allocations are an athermal design, acceptable mirror CTE homogeneity and mirror mount pad design. This paper will present the sensitivities and error budget used to predict the on-orbit mirror stability. The author requests that a paper given by Matt East from Harris come before this presentation if both are presented.
