Knight Optical's UV Fused Silica for Vacuum Windows | |
03 Jan 2018 Knight Optical can offer UV Fused Silica Windows for Vacuum Applications. UV Fused Silica is a relatively hard optical glass with a very low coefficient of thermal expansion. This means that it is a good choice for us in Vacuum applications, as any difference in temperature will not affect the optical performance. In addition to the above, UV FS has high transmission from UV to NIR meaning that there is little loss of image when it is used for a Vacuum Window/viewport and therefore the quality of the optical system is not compromised. Typical specs: Material: UV Grade Fused Silica Operating Wavelength 587nm Centring Tolerance Focal Length Tolerance: ± 0.2mm (<10mm) ±2.0% (10mm – 1000mm) Centre Thickness Tolerance ±0.2mm Surface Figure 3/ 3 (1) Surface Quality: Coating: Optional All our UV Fused Silica Lenses are fully inspected on their quality in our ISO 9001 certified, state-of-the-art Metrology laboratory, using our Trioptics Optispheric, and Starrett AV300 and Zygo Verifire XPZ. This allows us to work to the highest QA standards and meet the tolerance specifications on these precision components. Contact our technical sales team to discover how Knight Optical’s high quality UV FS lenses and superior service can improve your instrumentation and supply chain experience.
