| abstract | The present invention includes, as a component, B 2 O 3 : 1-30% in weight percentage; SiO 2 : 0-20%; La 2 O 3 : 25-55%; Gd 2 O 3 : 5-40%; Y 2 O 3 : 0-25%; Yb 2 O 3 : 0-10%; Ta 2 O 5 : 0-10%; Nb 2 O 5 : 1-30%; TiO 2 : 0-10%; ZrO 2 : 0.5-20%; WO 3: 0-10% ; ZnO: 0-15%; R 2 O: 0-10%; RO: 0-10%; Al 2 O 3: 0-10%; GeO 2 : 0-10%; Bi 2 O 3 : provides a high refractive index and low dispersion optical glass containing 0-10%. By reducing the content of Ta 2 O 5 from the glass component and introducing a suitable amount of a rare-earth oxide having a high refractive index and low dispersion effect, it has excellent light transmittance and is environmentally friendly and has a high refractive index and low refractive index. Dispersed optical glass is obtained. |
