| 摘要 |
The invention provides an optical glass having the desired high transmission ratio and high chromatic dispersion and capable of reducing the concavo-convex and fuzzy of the surface, and an optical element. The optical glass, based on the total mass of the glass calculated relative to the oxides, comprises 5.0 to 40.0 % by weight of P2O5, 10.0 to 60.0 % by weight of Bb2O5 and 5.0 to 45.0 % by weight of TiO2, and, based on the weight of oxides beside Sb2O3, comprises less than 1.0 % by weight of Sb2O3. Moreover, the optical element takes the optical glass as a base material. |
