5 mm ZnSe Round Optical Window, AR Coated

Product description

Zinc Selenide (ZnSe) windows are ideal for thermal imaging applications, particularly in the 8-14 μm and 10.6 μm CO2 laser bands. With a high transmittance of over 99.5% at 10.6 μm, these round windows ensure optimal performance in thermal and laser systems. Manufactured with advanced techniques in Hubei, they provide excellent optical quality and reliability, making them suitable for various environments, although care is needed due to the material’s softness.
