摘要： The invention provides an environment-friendly optical glass with high refractive index, low dispersion and high light transmittance. The optical glass includes 6%-17% of B2O3, 2-10% of SiO2, more than 25% but less than 45% of La2O3, 5-25% of Gd2O3, 0-3% of Nb2O5, more than 19% but less than 27% of Ta2O5, 0-16% of ZnO, 0-5% of BaO, 0-5% of CaO, 0-5% of SrO, 0-9% of ZrO2, 0-8% of Y2O3, 0-8% of Yb2O3, 0-5% of WO3, 0-2% of Li2O, Na2O and K2O, equal to 0.01% but less than 0.1% of Sb2O3 and 0-1% of SnO2 optical glass. The environment-friendly optical glass does not contain GeO2, and has refractive index of 1.85-1.90, Abbe number of 35-45, the corresponding wavelength below 440 nm when transmittance thereof reaches 80% and high transmittance.
