| titleOfInvention | Optical glass and optical element |
| abstract | The purpose of the present invention is to provide an optical glass that has a refractive index and an Abbe number both within a desired range and that contributes to weight reduction and stability of an optical instrument at a lower cost. The optical glass contains B in mass percent 2 O 3 5.0 to 30.0% of La 2 O 3 30.0 to 60.0%, the sum of the mass of the oxides (ZrO) based 2 +Nb 2 O 5 +Ta 2 O 5 +WO 3 ) Below 20.0%. The optical glass has a refractive index nd of 1.85 or more, an Abbe number vd of 30 or more, and a specific gravity of 5.00 or less. |
