Abstract
The invention is directed to photomachinable glass compositions having a controllable or tunable photosensitivity, and to a method for making such compositions. The compositions of the invention contain titania (TiO) in an amount in the range of greater than 0.01 wt. % to 2 wt. % added to any known photomachinable glass composition. In one embodiment the TiOin an amount in the range of greater than 0.01 wt. % to 1 wt. %. An example of a photomachinable glass of the invention is one having a composition having, in weight percent (wt. %) of 65-80% SiO, 15-20% LiO, 1-4% NaO, 1-4% KO, 2-10% AlO, 0-3% ZnO, 0-0.15% SbO, 0-0.015% CeO, 0-0.001% Au, 0-0.015% Ag and >0.01% to 2% TiO, and the sum of Au+Ag is greater than zero.
