Where to Buy Optical Windows

Edmund Optics’ optical windows are offered in a variety of substrates, such as germanium (Ge), silicon (Si), N-BK7, UV fused silica, zinc selenide (ZnSe), and potassium bromide (KBr). Multiple anti-reflection coating options are available for the ultraviolet (UV), visible, or Infrared (IR).

Shanghai Optics Inc state of the art factory is able to manufacture both large optical windows and micro windows for nano-sized optical assemblies. A wide variety of optical substrates are available to choose from, and since production is carried on in-house our design team, will be able to match your exact specifications when carrying out your order.

Artifex Engineering offers custom optical windows in almost any shape and design, including cut-outs and drillings. A wide range of optical substrates are available including N-BK7, fused silica, sapphire, Ge, ZnSe and more. AR coatings are generally applied to both surfaces of a window. In addition, Artifex offers custom coatings such as diamond-like carbon (DLC) coatings for the infrared (germanium, silicon). Visit our product page for more information. We look forward to your inquiry.
