Abstract

UVISS is a small telescope of 50 cm aperture designed for accommodation on the International Space Station, and it will employ multilayer coatings for imaging in the near UV (130 - 260 nm) and possibly also far UV (90 - 115 nm) bands. Near UV filters have been designed using MgF₂, BaF₂, Al₂O₃, SiO₂, Y₂O₃, and the far UV filter has been designed using LiF and Y₂O₃. Tests are in progress on some of these coatings, including trade-off's between multilayers and Indium filters short-wards of Lyα. The first results are encouraging, since they show that the technique appears to be feasible.
