Title:
HIGH-REFRACTIVE AND HIGH-DISPERSION OPTICAL GLASS AND OPTICAL ELEMENT
Document Type and Number:
WIPO Patent Application WO/2022/193797
Kind Code:
A1
Abstract:
The present invention provides a high-refractive and high-dispersion optical glass. The high-refractive and high-dispersion optical glass comprises components as represented in percentage by weight: 8-25% of P2O5; 30-60% of Bi2O3; 15-35% of Nb2O5; and 3-25% of WO3, wherein Bi2O3/(Nb2O5+P2O5) is 0.6-2.3. By means of reasonable component design, the optical glass obtained in the present invention has a relatively low transition temperature while having expected refractive index and Abbe number, and is suitable for precise dropping molding or precise compression molding.
