Fused silica glass windows
N-BK7 windows are ideally suited for industrial applications. Available uncoated or with a MgF2 anti-reflection coating, windows are often used as a protective element between two environments.

Fused Silica features high transmission from 200nm to 2.2μm with a low coefficient of thermal expansion, making it ideal for the most demanding ball lens applications in the ultraviolet, visible, and near infrared spectra. Ball lenses are commonly used for improving signal coupling between fibers, emitters, and detectors, as well as objective lenses in endoscopy and bar-code scanning applications. Half-ball lenses simplify handling and integration.
