HOMOGENOUS SILICA-TITANIA GLASS

A glass including silica and titania is disclosed. An average hydroxide concentration of a plurality segments of the glass is in a range from about 600 ppm to about 1300 ppm, an average titania concentration of the plurality of segments is in a range from about 6 wt.% to about 12 wt.%, and each segm...

Zusammenfassung:	A glass including silica and titania is disclosed. An average hydroxide concentration of a plurality segments of the glass is in a range from about 600 ppm to about 1300 ppm, an average titania concentration of the plurality of segments is in a range from about 6 wt.% to about 12 wt.%, and each segment of the plurality of segments has a length of about 12.7 mm, a width of about 12.7 mm, and a height of about 7.62 mm. The hydroxide concentration of each segment is measured using a Fourier transform infrared spectroscopy in transmission, the refractive index is measured using an optical interferometer with a 633 nm operating wavelength and a resolution of 270 microns x 270 microns pixel size, and the average titania concentration is determined based upon the measured refractive index.
