What are the specifications of Zinc Selenide (ZnSe) 8-12 IR Lens?

Description: A high efficiency, anti-reflectance coating with moderate durability for Zinc Selenide optics, providing excellent transmittance in the 8–12µm spectral band.

Application: Thermal imaging systems & FLIR systems.

Spectral Performance: The following spectral transmission value is based on coating both sides of a 1mm thick Zinc Selenide substrate with ZnSe 8–12.

Spectral Performance: @ 8-12µm
Transmission: 98% average
Reflection: 1% average per surface

Environmental Performance: The coating passes the following environmental tests specified in MIL-F-48616 & MIL-C-48497:

Adhesion: Cellophane tape removal test
Abrasion: Moderate (No sign of deterioration such as scratches or streaks when abraded with a dry, clean cheesecloth pad)
Temperature: -80°F to +160°F (-62°C to 71°C) for 2 hours at each temperature.

The coating performance specified herein is typical of this particular coating and does not preclude adherence to other specifications on a case by case basis.
