Abstract:
An ultraviolet light transmitting glass contains, in molar percentage on an oxide basis, 55% or more and 80% or less of SiO 2 ; 12% or more and 27% or less of B 2 O 3 ; 4% or more and 20% or less of R 2 O in total, where R represents at least one alkali metal selected from a group consisting of Li, Na, and K; 0% or more and 5% or less of Al 2 O 3 ; 0% or more and 5% or less of R′O in total, where R′ represents at least one alkaline earth metal selected from a group consisting of Mg, Ca, Sr, and Ba; 0% or more and 5% or less of ZnO; and 1.5% or more and 20% or less of ZrO 2 . The ultraviolet light transmitting glass with a thickness of 0.5 mm has a transmittance of 70% or more at a wavelength of 254 nm.

Claim (Index 8):
The ultraviolet light transmitting glass according to  claim 1 , wherein\n a deterioration in the transmittance at the wavelength of 254 nm determined by the following expression (1) is 5% or less in an ultraviolet light irradiation test.\n Deterioration [%]=[( T 0\u2212 T 1)/ T 0]\u00d7100\u2003\u2003Expression (1) \n where T0 indicates initial transmittance of the ultraviolet light transmitting glass at the wavelength of 254 nm, the ultraviolet light transmitting glass having a thickness of 0.5 mm and optically polished surfaces opposite to each other, and T1 indicates transmittance of the ultraviolet light transmitting glass at the wavelength of 254 nm after irradiated with ultraviolet light having the wavelength of 254 nm and an intensity of 5 mW/cm 2  for 100 hours.
