ABSTRACT:
Optical glass containing bismuth oxide having good defoamability. The Optical glass contains, as % by mass, from 10 to less than 90% of a Bi2O3 component and at least 0.1% of a TeO2 and/or SeO2 component. The optical glass is on Grade 4 to Grade 1 in “JOGIS12-1994, Method for Measuring Bubbles in Optical Glass”. By controlling the amount of RO component (R is at least one selected from a group consisting of Zn, Ba, Sr, Ca, Mg) and Rn2O component (Rn═Li, Na, K, Cs), the clarifying time may be shortened.
