Abstract
Optical glass is disclosed which has an increased resistance to solarization and irradiation as well as little or no undesirable coloring. This glass is designed to exhibit as many properties having optimal values as possible. The silicate glass used is free of alkaline earth metal oxides and incorporates CeO.sub.2 and both zinc and strontium ions in very small concentrations. The latter two materials further improve the solarization and irradiation resistance properties of the glass. Furthermore, as the zinc and strontium ions are effective when used in low concentrations, they serve to minimize any undesirable glass coloring.
