UV Fused Silica High-Precision Windows are available in four sizes ranging from Ø1/2" to Ø2" and a rectangular 25 mm x 36 mm size. Round windows can be purchased from stock uncoated (185 nm - 2.1 μm) or with one of our four low-loss standard broadband antireflection coatings deposited on both surfaces: -UV (245 - 400 nm), -A (350 - 700 nm), -B (650 - 1050 nm), or -C (1050 - 1700 nm). While uncoated windows have typical losses of about 4% per surface, the AR coatings reduce this to Ravg < 0.5%. These AR coatings provide good performance for angles of incidence (AOI) between 0° and 30°

UV-grade fused silica is well-suited for applications that benefit from increased transmission deeper into the UV than N-BK7. UV fused silica also offers a lower index of refraction for a given wavelength, better homogeneity, and a lower coefficient of thermal expansion than N-BK7.

offers flat windows fabricated from N-BK7, UV Fused Silica, Sapphire, Calcium Fluoride, Magnesium Fluoride, Potassium Bromide, Infrasil, Zinc Selenide, Silicon, Germanium, or Barium Fluoride. Our laser windows have a wavelength-specific AR coating centered around commonly used laser wavelengths and an optional wedge, while our precision windows are offered with or without a broadband AR coating.
