Paper Abstract

Normal incidence thin-film interference mirrors and filters, using MgF2 as the spacer material, were designed to image the O II 834 angstroms airglow and to reject the intense H I radiation at 1216 angstroms. Peak mirror reflectance of 60 can be obtained with a passband 200 angstroms wide centered on 834 angstroms. An interference filter is designed to transmit 834 angstroms and to attenuate 1216 angstroms radiation. The throughput at 1216 angstroms is smaller than the throughput at 834 angstroms by a factor of 500.
