Product Family Description

Low Coefficient of Thermal Expansion
Visible to Near Infrared Transmission
High Resistance to Thermal Shock

BOROFLOAT® Borosilicate Windows are ideal for high temperature and harsh environment applications. Unlike common borosilicate that is drawn flat, BOROFLOAT® is produced by a float technique that yields superior surface flatness — typically 4 - 6λ per inch. BOROFLOAT® is about three times more resistant to thermal shock than standard soda lime glass.
