Abstract
Optical glass filters are provided that include a filter glass showing an optimized transmission spectrum which has a high transmission in the wave length range of 300 to 400 nm and a very low transmission in the visible wave length range. The glass has an especially high optical quality and is excellently suitable as an optical filter for generating UV light without a proportion of visible light. The optical glass filters include the components nickel oxide and cobalt oxide.
