Abstract:
The present invention is directed at a family of glasses capable of absorbing UV radiation and filtering yellow light in the visible region of the spectrum, the family of glasses having a composition consisting essentially, in terms of weight percent on the oxide basis, of: 55-95.7% SiO2, 0-28% B2O3, 0.5-18% Al2O3, 0-4% SrO, 0-13% BaO, 0-13% CaO, 0-8% MgO, 0-7.5% Na2O, 0-9.5% K2O, 0-1.5% Li2O, 0-1.5% Sb2O3, 0.4-4.5% Nd2O3, and 0.1-1% CeO2. Glasses of the present invention are capable of employment as envelopes for tungsten-halogen lamps and other high temperature light sources, as well as sealed-beam incandescent headlights. Also, the glasses can be used as for other applications where high contrast and enhanced visible properties of transmitted or reflected visible light can be a benefit, such as opthalmic glass, computer screens with enhanced contrast properties, or glass hosts for lasers.
