Abstract
An optical glass, wherein components thereof are represented by weight percentage, including: 1-15% of SiO; 5-20% of BO; 25-50% of LaO; 1-12% of ZrO; 5-20% of TiO; 6-35% of RO, and the RO is total content of MgO, CaO, SrO, and BaO. Through rational component design, the optical glass has low density while having desired refractive index and Abbe number, which meets the lightweight application of optical instruments.
