Abstract
Titanium oxide containing borosilicate glasses, which have been produced without the use of arsenic and antimony compounds, are provided. An environmentally friendly refining method for providing titanium oxide containing borosilicate glass is also provided. The method includes using oxygen containing selenium compounds as refining agents to provide glasses with good transmittance values in the infrared range and show no disturbing discolorations. The glasses of the present disclosure are particularly suitable for the production of IR light conductors, cover glasses for photo sensors, and UV filters.
