光学玻璃、预成型体及光学元件
Abstract:
本发明提供光学玻璃和使用该光学玻璃的预成型体及光学元件，所述光学玻璃具有高折射率(nd)、具有更低的阿贝数(νd)、且具有高可见光透射率。光学玻璃以质量％计，含有Bi2O3成分及B2O3成分，分光透射率为70％的波长(λ70)为500nm以下。预成型体及光学元件由该光学玻璃形成。
Abstract(English):

The invention provides optical glass, and a performed body and an optical element using the optical glass. The optical glass has a high index of refraction (nd), a low abbe number (vd) and a high visible light transmittance. The optical glass, by mass%, Bi2O3 and B2O3, and the wave length (lambda 70) with 70% in spectral transmission is below 500 nm. The preformed body and the optical element are formed by the optical glass.
