Paper Abstract

Many satellite-borne measurement applications require lightweight, reflective near diffraction limited telescopes with wide spectral bands (UV/visible to LWIR), for operation in space environments and over wide temperature ranges. Emerging silicon carbide (SiC) technology provides an attractive material for these telescope applications. The present paper describes the design and analysis of a 50 cm dia. aperture on-axis three mirror re-imaging SiC telescope, including the structure and a 'GOES like' scan flat for the GEO application. Optical, thermal and structural design and analyses are described for the demonstration hardware. Demonstration mirrors and structural hardware have been fabricated, tested and compared to design analyses with excellent agreement.
