Ultraviolet light absorbing glass
Abstract:
An ultraviolet light absorbing glass according to the present invention includes 1.6% or more of t-Fe2O3, more than 1.0% of TiO2, and 0.016% or more of CoO. The ultraviolet light absorbing glass has t-Fe2O3/TiO2 of 1.2 or more, and an ultraviolet light transmittance (TUV400) at a sheet thickness of 3.1 mm of 2.0% or less, a ratio of visible light transmittance (TVA)/TUV400 of 10 or more, and a dominant wavelength (λD) of 555 nm or less.
