UV Grade lenses are precision manufactured using HPFS Fused Silica Standard Grade. In order to provide excellent transmission characteristics and higher operating temperature, synthetic fused silica lenses also exhibit an exceptional inclusion specification and chemical purity. These lenses make a superior choice for many laser and imaging applications, particularly those involving ultraviolet wavelength. BTMT can offer the laser grade surface quality and tight radius tolerance.

 
HPFS Standard Grade, Corning code 7980, is a high purity synthetic amorphous silicon dioxide manufactured by flame hydrolysis. The noncrystalline, colorless, silica glass combines a very low thermal expansion coefficient with excellent optical qualities and exceptional transmittance in the ultraviolet. It is certified to meet T external ¡Ý80%/cm@185nm, when measured through a polished sample.
