ICQNS16CF-E
Demountable substrate vacuum viewport flanges are an economical “alternative” to fused and/or brazed viewport solutions. They are available with Accu-Sol™ high-transmission glass or quartz (fused silica) substrate materials. Quartz versions are offered in coated and uncoated configurations. Substrate Transmission varies by material and/or coating option. Accu-Sol™ glass has greater than 90% transmission over the 350~2200nm spectral range. Quartz substrates are available with specially formulated broadband (BBAR) anti reflection coatings for better than 99% transmission in the following discrete wavelength ranges… 290~370nm (UV), 350~700nm (A), 650~1050nm (B), 1050~1620nm (C). Uncoated quartz transmission varies from 70~95% over the 200~2200nm range.
