Abstract

The Multi-Spectral Solar Telescope Array (MSSTA) is a sounding rocket borne observatory for investigations of the Sun in the soft x-ray/EUV and FUV regimes of the electromagnetic spectrum. At soft x-ray wavelengths (),\ < 100 A), the MSSTA utilizes single reflection multilayer coated Herschelian telescopes. For selected wavelengths in the EUV (100 - 1000 A) the MSSTA employs five doubly reflecting, multilayer coated Ritchey-Chretien and two Cassegrain telescopes. In the FUV ()\ > 1000 A) the MSSTA utilizes two Ritchey-Chretien telescopes, with optics coated with thin film interference coatings. In this paper, we describe the interferometric alignment, testing, focusing, visible light testing, and optical performance characteristics of the Ritchey-Chretien and Cassegrain telescopes.
