摘要：
A non-lead optical glass consisting essentially of, as represented by mol %, from 45 to 75% of Bi2O3, from 12 to 45% of B2O3, from 1 to 20% of Ga2O3, from 1 to 20% of In2O3, from 0 to 20% of ZnO, from 0 to 15% of BaO, from 0 to 15% of SiO2+Al2O3+GeO2, from 0 to 15% of MgO+CaO+SrO, from 0 to 10% of SnO2+TeO2+TiO2+ZrO2+Ta2O3+Y2O3+WO3 and from 0 to 5% of CeO2, wherein Ga2O3+In2O3+ZnO≧5%. An optical fiber comprising the above non-lead optical glass as a core.
