Athermal Superiority: SiC vs. Aluminum-Glass Telescopes for SmallSat Applications

 INTRODUCTION Optical Telescope Assemblies (OTAs) implemented in silicon carbide (SiC) provide performance advantages for space applications but have been predominately implemented in the government sector. A new generation of lightweight and thermally-stable designs is commercially available, expanding the application of SiC to small satellites. One of the major challenges in satellite telescope design is the ability to maintain performance in the thermal environment of low-earth…
