In one embodiment the present disclosure is directed to a silica-titania glass with an internal transmission of >90%/cm at wavelengths from 340 nm to 840 nm. In another embodiment the internal transmission is >93%/cm at wavelengths from 340 nm to 840 nm. In a further embodiment the internal transmission is >95%/cm at wavelengths from 340 nm to 840 nm. In another embodiment the disclosure is directed to a silica-titania glass with an overall transmission through an optic made of the glass is >84% at wavelengths from 340 nm to 840 nm. In another embodiment overall transmission through an optic made of the glass is >86% at wavelengths from 340 nm to 840 nm. In a further embodiment the overall transmission through an optic made of the glass is >88% at wavelengths from 330 nm to 840 nm. In a further embodiment the silica-titania glass has a Ti+3 concentration level [Ti3+] less than 3 ppm by weight.
A silica-titania glass consisting of 7-10 wt. % titania and 90-93 wt. % silica and said glass has an internal transmission of greater than 95%/cm over the wavelength range of 340 nm to 840 nm, a fictive temperature less than 900° C. in combination with greater than 600 ppm [OH] by weight, and said glass having a hydrogen (H2) concentration of less than 2×1017 hydrogen molecules/cm3.
A silica-titania glass consisting of 7-10 wt. % titania and 90-93 wt. % silica and said glass has an internal transmission of greater than 95%/cm in the wavelength range of 340 nm to 840 nm, a fictive temperature less than 900° C. in combination with greater than 600 ppm a [OH] by weight, and said glass having a hydrogen (H2) concentration of less than 2×1016 hydrogen molecules/cm3.
A silica-titania glass consisting of 7-10 wt. % titania and 90-93 wt. % silica and said glass has an internal transmission of greater than 95%/cm in the wavelength range of 340 nm to 840 nm, a fictive temperature less than 900° C. in combination with greater than 600 ppm [OH] by weight, and said glass having a hydrogen (H2) concentration of less than 0.1×1017 hydrogen molecules/cm3.
