Field corrector for the Ultraviolet Italian Sky Surveyor on the International Space Station (UVISS): ion beam figuring and application of the multilayer filters

摘要

UVISS is a square aperture Ritchey-Chretien telescope of 45x45 cm designed for accommodation on the International Space Station. The designed field corrector can give a corrected field of view larger than that required by the project; the optical surface of the corrector will be figured using the ion beam figuring technique, with an expected extremely good optics quality. UVISS will employ multilayer coatings for imaging in the near UV (130 - 260 nm) and possibly also far UV (90 -115 nm) bands.
