ANISOTROPIC GLASS |
摘要 |
The present invention relates to an anisotropic glass containing, in terms of mol % on the basis of oxides, P2O5 in a content of from 45 mol % to 57 mol %, two or more kinds of alkali metal oxides selected from the group consisting of Li2O, Na2O, K2O, Rb2O, and Cs2O in a total content of from 30 mol % to 54 mol %, and at least one polyvalent element oxide other than P2O5 in a total content of from 0.1 mol % to 20 mol %, and having a birefringence of 30×10−6 or more. |
