    Quartz Fused Silica Windows

    • Introduction

    Quartz Fused Silica Windows

    Hyperion Optics supplies a wide range of custom Quartz, UV fused silica and IR fused quartz windows through UV to infrared spectrum.


    Custom quartz windows: have a useful transmission range from 0.26 visible to 2um in the infrared, which working temperature up to 1050°C, with typical AR coating applied, quartz windows are suitable for most visible to infrared applications.

    Custom UV grade fused silica windows: We have access to both Corning 7980 and Chinese equivalent JGS1 both working well from 0.17um, suitable for spectroscopic application in UV range.
