Abstract

The present invention relates to a boroaluminosilicate glass which exhibits excellent UV transmission. In particular, the present invention is directed at an alkali fluorine-doped boroaluminosilicate glass comprising, in mole percent on the oxide basis, of 30-80 % SiO2, 1-20 % Al2(O, F2)3, 5-35 % B2O3, 5-20 % R2O, where R is Li, Na, K, Rb or Cs, and an amount of up to 12 % of F. The glass possesses an R/Al molar ratio of between 0.4 to 3 and an F/O molar ratio of no greater than 0.35. The alkali fluorine-doped boroaluminosilicate glass of the present invention exhibits a UV transmission at 300 nm, of greater than 80 %/mm.
