Quartz, UV fused silica window and IR fused quartz windows for applications in the UV though to the near infrared regions.
Quartz windows: Quartz material is stronger than glass, can be used at temperatures up to 1050°C and has a high average transmission of over 80% from 260nm to 2500nm. Our stock ranges of quartz windows are useful for most UV applications other than fluorescence applications as quartz material fluoresces. Our stock quartz windows are also not useful in wavelength applications less than 250nm where transmission drops to just 72%. For deep UV at 175-185nm UV fused silica is a more suitable choice of material.
