N-BK7  Optical Windows-Fused Silica Windows-Sapphire Glass Windows

N-BK7 optical windows are the most common type on many products.

PBL Optics’ optical windows or optical wafers are flat on both surfaces, with square, rectangle, round shape. They can offer protective shielding for light sensitive applications. Coated or un-coated windows are available. They may not cause the change in the magnification of a optical system. Brewster windows are designed for eliminate p-polarization reflectance

PBL Optics can make many kinds of substrates, such as N-BK7, BK7,B270, sapphire, fused silica, germanium (Ge), silicon (Si), zinc selenide (ZnSe),  potassium promide (KBr) and etc. For different application in the ultraviolet (UV), visible, or infrared (IR), coatings are optional.

As a professional manufacturer and exporter of achromatic lenses here in China, PBL optics can make custom optical windows for the specific application of your imaging system. If you want to buy them, let’s discuss your application.
