摘要:
Provided with the following glass components: 8 to 19.5% B2O3, 4.5 to 9% SiO2, 0 to 10% GeO2, 7 to 12.5% BaO, 0 to 14% MgO, 0 to 0.4% Li2O, 15 to 34% La2O3, 3.5 to 10% Y2O3, 8 to 13.5% TiO2, 0 to 7% ZrO2, 0 to 11% Nb2O5, and 1 to 9% WO3 by weight, wherein B2O3/SiO2 is at least 1.0, La2O3+Y2O3+ZrO2+Nb2O5+WO3 is no more than 54%, and B2O3+SiO2+GeO2+BaO+MgO+Li2O+La2O3+Y2O3+TiO2+ZrO2+Nb2O5+WO3 is at least 98%.
