Survey of materials used in 3 filters, developed for use in rocket borne ultraviolet nondispersive photometers, with effective wavelengths of 2700, 2600, and 2210A; materials used were 2200A interference filters, NiSO4(H2O)6 crystals, KCl:KBr:Pb crystals, cation-X, and Corning filters 9-54 and 7-54; filters have transmittances of 0.16, 0.23, and 0.10 at respective effective wave-lengths with corresponding bandwidths of 320, 200, and 330A.
