Spacecraft spectrometer or interferometer optical unit structure has optical sub units in precisely made ceramic construction on less precise ceramic support structure

摘要

A spacecraft spectrometer or interferometer optical unit structure has optical sub units (2, 3, 4) with optical elements and reflectors (8-18) mounted to accurately made stiff light thermally stable ceramic sub structures (5, 6, 7) such as Silicon Carbide attached to a less accurately made stiff light thermally stable ceramic material support structure using for example Carbon/Silicon Carbide.
