More Information
Summary:The invention provides optical glass, which comprises the following components in percentage by weight: 16 to 33 percent of P2O5; nb2O5: 40% to 55%; 1 to 13 percent of TiO2; 1 to 15% of BaO; 0.5 to 15 percent of Na2O; znO: 0-8%, wherein ZnO/(Na2O + TiO2) is 2.0 or less. Through reasonable component design, the optical glass obtained by the invention has a higher bubble degree grade while having expected refractive index and Abbe number, and meets the use of high-performance optical instruments. 本发明提供一种光学玻璃，其组分以重量百分比表示，含有：P2O5：16～33％；Nb2O5：40～55％；TiO2：1～13％；BaO：1～15％；Na2O：0.5～15％；ZnO：0～8％，其中ZnO/(Na2O+TiO2)为2.0以下。通过合理的组分设计，本发明获得的光学玻璃在具有期望的折射率和阿贝数的同时，具有较高的气泡度等级，满足高性能光学仪器的使用。
