Product Description

Product Description
Optical windows are falt, plane parallel plates which are often used as protective barriers for electronic sensors or detectors from outside environments. When selecting windows, please consider materials, transmission, scattering, parallelism and resisitance to certain environment or mechanical properties of the substrate.

N-BK7 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.
