摘要: To Provide a polarizing glass with better weatherability than conventional polarizing glasses, affording high long-term reliability without the above-described surface deterioration. To provide an optical isolator employing polarizing glass of improved weatherability, affording good weatherability and high reliability for extended periods.[Means for Solving] A polarizing glass comprising geometrically anisotropic particles dispersed in an oriented manner in at least one surface layer of a glass base body. The glass base body does not comprise an oxide of alkali earth metal and PbO, and consists of borosilicate glass comprising at least one additive component selected from the group consisting of Y2O3, ZrO2, La2O3, CeO2, Ce2O3, TiO2, V2O5, Ta2O5, WO3, and Nb2O5, and the geometrically anisotropic metal particles are metallic cupper particles. An optical isolator employing the polarizing glass.
