New Family Of Glass Good For Lenses

Researchers at the Pennsylvania State University have developed a new composition of germanosilicate glass by adding zinc oxide, which has properties excellent for lens applications. This new family of zinc germanosilicate glass has a high refractive index comparable to that of pure germania glass, high transparency, good ultraviolet-shielding properties, and good glass forming ability, making it a practical choice for manufacturing on a mass scale. A patent has been filed for the glass - for more information please visit: htts://news.psu.edu
