1. An optical glass, comprising:
6 wt % to 10 wt % of B2O3; 10 wt % to 15 wt % of B2O3 and SiO2, wherein the content of B2O3 is more than that of SiO2; 27 wt % to 32 wt % of La2O3; 0 wt % to 5 wt % of Gd2O3, Y2O3 and Yb2O3, wherein the content of Gd2O3 is 0 wt % to 3 wt %; more than 19 wt % but less than 25 wt % of TiO2; more than 8 wt % but less than 15 wt % of Nb2O5; 0.5 wt % to 5 wt % of ZnO; 0 wt % to 2 wt % of WO3; 2 wt % to 10 wt % of ZrO2; more than 10 wt % but less than 15 wt % of BaO; 0 wt % to 5 wt % of CaO, SrO and MgO, wherein the content of SrO is 0 wt % to 3 wt %; and 0 wt % to 0.1 wt % of Sb2O3;
wherein a ratio of the content of TiO2 to a total content of TiO2, WO3 and Nb2O5 is (005-0.75) to 1, andwherein a mass ratio of TiO2 to BaO is (1.3-2.4) to 1. |
