Abstract:
Provided is an optical glass having a high refractive index, a low density, and good manufacturing properties. An optical glass having: a refractive index (n d ) of 1.68 to 1.85; a density (d) of 4.0 g/cm 3  or less; and a temperature where a viscosity of glass becomes log η=2 of 950 to 1200° C., and an optical component using the optical glass are provided. This optical glass has the high refractive index, the low density, and the good manufacturing properties, and is suitable as the optical glass of wearable equipment, for a vehicle mounting, for a robot mounting, and so on.

Claim (Index 21):
