Coated ZnSe Windows

Windows are frequently used in optical systems to separate the environment in one part of the system from another, such as to seal vacuum or high-pressure cells. Because the infrared transmitting material has a high index of refraction, an anti-reflection coating is typically applied to windows to minimize losses due to reflections.

Below is the typical transmission of an AR coated, ZnSe window at 0° incidence:

Dimensional Tolerance	Diameter: +0.0,-0.1 Thickness: +0.1,-0.1
Edge Thickness Variation (ETV)	<= 3 arc minutes
Clear Aperture (polished)	90% of diameter
Surface Figure at 0.63µm	1.0 fringe/0.5 fringe
Scratch-Dig	20-10 to 80/50
AR Coating per Surface at 10.6µm	R< 0.20%
