Abstract

1406134 Optical glass TALLINSKY STEKOLNY ZAVOD TARBEKLAAS 1 June 1973 26159/73 Heading C1M An optical glass formed from barium monofluorpphosphate comprises (in mole per cent) the balance, if any, consisting of other compatible constituents. The glass may additionally comprise 0À1-20 mole per cent GaF 3 . The glass may have a refractive index (n D ) in the approximate range 1À54-1À60, and a dispersion coefficient (v) in the approximate range 68-78.
