Abstract | The invention provides optical glass as well as a glass prefabricated part, an optical element and an optical instrument which are made of the optical glass. The optical glass comprises the following components by mole percent: 1-10% of Si < 4 + >, 25-40% of B < 3 + >, 20-40% of La < 3 + >, 0-15% of Gd < 3 + >, more than 0 and less than or equal to 10% of Y < 3 + >, 1-10% of Zr < 4 + >, 1-10% of Nb < 5 + >, 8-25% of Ti < 4 + > and 0-10% of W < 6 + >, and (Nb < 5 + > + Ti < 4 + > + W < 6 + >)/Y < 3 + > is 26-46. The invention has the advantages of scientific design, reasonable formula, excellent chemical stability, high refractive index and low production cost.
本发明提供了一种光学玻璃及由该光学玻璃制成的玻璃预制件、光学元件和光学仪器。本发明的光学玻璃的组成按摩尔%表示,含有Si4+:1-10%、B3+:25-40%、La3+:20-40%、Gd3+:0-15%、Y3+:大于0小于等于10%、Zr4+:1-10%、Nb5+:1-10%、Ti4+:8-25%、W6+:0-10%,其中(Nb5++Ti4++W6+)/Y3+为26-46。本发明设计科学,配方合理,具有优异的化学稳定性,其折射率高,生产成本低。 |
