Abstract

This invention provides an optical glass and the manufacture method of the same. The optical glass of this invention may suppresses the generation of Pd micro particles and does not decrease its clearness effect even uses a liqueting equipment that made from Pt containing refractory material to liquefy the glass raw materials of Sb containing composition as clarifier. The feature of the Sb containing optical glass of this invention is the ratio of Sb3+/total Sb being above 0.45.
