Paper 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.
