The optical glass is ideal for the transmission of light even after being exposed to X-rays, and has a high refractive index. The optical glass comprises, by mass % in terms of oxide versus the glass total mass, 1.0% to 60.0% of an SiO2 component, and one or more selected from the group consisting of an La2O3 component, ZrO2 component, TiO2 component, Nb2O5 component, and Ta2O5 as essential components. The optical glass has a refractive index (nd) of 1.50 or greater, and has a light intensity recovery rate of 45% or greater when the glass having been irradiated with X-rays with a dose of 2.5 Gy is irradiated with light of a xenon lamp for 11 hours.

摘要： Provided is an optical glass having high refractivity and high dispersibility, having good moldability in precision pressing, and having high transmittance and good internal quality, of which the transmittance reduction with time is prevented. The optical glass has a Pt content of at most 1.5 ppm, and is characterized in that, when a sample of the glass polished on both surfaces and having a thickness of 10 mm is irradiated with UV and/or visible light at a light-receiving energy of at most 0.4 mW·cm−2 for at least 200 hours, then the difference in the internal transmittance to light having a wavelength of 420 nm, before and after the irradiation (before irradiation—after irradiation) of the sample, as calculated in terms of the sample having a thickness of 10 mm, is at most 0.1.
