Abstract
ZERODUR®’s supreme thermo-mechanical stability is enabling for high-performance telescopes, including mirror substrates and even the precision metering structure. For on-orbit high-resolution SmallSat telescopes, tight dimensional control may be passively maintained, even while experiencing continuously changing Solar and Earth thermal view factors. This stability is a vast improvement over implementation in alternate materials like aluminum. ZERODUR®’s thermal and strength characteristics are comprehensively described via ~ 100 scientific publications. Innate stability, decades of spaceborne heritage and expert machining and lightweighting from SCHOTT offers special ZERODUR® cost-effective solutions for SmallSat Telescope Design-to-Cost paradigms, even for constellation level implementation. The latest information for such designs is described, including that for designing with ZERODUR®’s thermal ultrastability, with its comprehensive strength data, with its lightweighting, and even with ultrastable, cost-effective all-ZERODUR® structures. A paradigm proven capable of reducing the time and cost in optical fabrication by up to 50% is summarized. Other key characteristics, for example demisability, radiation resilience, mounting mirrors and even EAR/ITAR supply chain management will be described.
