High-Performance ZnSe Windows – Low Absorption IR Windows for CO₂ Lasers & Thermal Imaging
Optimize your infrared optical system with our premium Zinc Selenide (ZnSe) Windows, engineered for maximum transmission across a broad spectral range from 0.5 µm to 22 µm. Featuring extremely low absorption coefficient (< 0.0005 cm⁻¹ at 10.6 µm) and high thermal conductivity, ZnSe windows are the industry standard for CO₂ laser output couplers, vacuum feedthroughs, and thermal imaging protective
