Zinc Selenide is suitable for applications in the IR band (8 to 14 µm) and is often used as a IR viewport window for thermography. We provide a large variety of ZnSe windows for vacuum viewports suitable for ISO-K, KF and СА flanges.

BBAR coating for 2-13µm and 8-12µm can be applied on ZnSe windows upon request.
