Product Description
Material:1: Fused silica quartz glass (Silica Glass ,Quartz Glass )
A) Optical quartz glass
Far Ultraviolet quartz glass (JGS1)UV Grade
Ultraviolet quartz glass (JGS2) Optical grade
Infrared optical quartz glass ( JGS3)

C) K9 Glass
D) Borosilica Glass including 80% SiO2Optical glass for Fused silica material Fused Silica is formed by chemical combination of silicon and oxygen. Fused Silica is perfect optical material due to its good UV and IR transmission, low coefficient of thermal expansion. It has high stability and resistance to thermal shock over large temperature excursions, wide temperature operating range and high laser damage threshold.Specifacation| Parameter | Standard Grade | Precision Grade | Ultra-precision Grade |
