Paper Abstract

We report the design of multilayer reflective filters for the self-filtering cameras of the NUVIEWS project. Wide angle self-filtering cameras were designed to image the CIV (154.9 nm) line emission, and H2 Lyman band fluorescence (centered at 161 nm) over a 20 degree(s) X 30 degree(s) field of view. A key element of the filter design includes the development of (pi) -multilayers optimized to provide maximum reflectance at 154.9 nm and 161 nm for the respective cameras without significant spectral sensitivity to the large cone angle of the incident radiation. We applied self-filtering concepts to design NUVIEWS telescope filters that are composed of three reflective mirrors and one folding mirror. The filters with narrowband widths of 6 and 8 nm at 154.9 and 161 nm, respectively, have net throughputs of more than 50% with average blocking of out-of-band wavelengths better than 3 X 10-4%.
