Knight Optical (UK) Ltd Fused Quartz Window (JGS2) 25mmdia x 3mmthk Uncoated WHQ2500

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. Quartz windows are useful for most UV applications other than fluorescence applications as quartz windows fluoresce. 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. Our stock quartz windows can also be antireflective coated to increase transmission performance. We offer a range of standard fused quartz windows (JGS2) direct from stock, Quartz is also available in large 1000x1000mm sheets so large custom quartz windows to any shape or size can be produced. Please contact our technical sales team for more information about your custom requirements.
