Solid organic filters for 2000 A to 3000 A.
Earlier work on the development of organic, narrow bandpass solution filters with transmittance maxima in the 2000-3000-A range is extended to the fabrication of solid filters using a polymethyl siloxane resin as the host material. Three transmission filters are described having maxima at 2250 A, 2265 A, and 2840 A, respectively, with bandwidths <or=225 A. Transmittance and spectral response curves with CsTe photocathodes are given. Results of environmental tests show that these filters are well suited for balloon and space missions.
