High refractive index glass
摘要：
Provided is a high refractive index glass, comprising, as a glass composition in terms of mass %, 0 to 10% of B2O2, 0.001 to 35% of SrO, 0.001 to 30% of ZrO2+TiO2, and 0 to 10% of La2O2+Nb2O5, having a mass ratio of BaO/SrO of 0 to 40 and a mass ratio of SiO2/SrO of 0.1 to 40, and having a refractive index nd of 1.55 to 2.3.
