Product Overview
Engineered for high-performance infrared systems, our Zinc Selenide (CVD ZnSe) Stepped Windows offer exceptional broadband transmission across the mid-wave (MWIR) and long-wave infrared (LWIR) spectra. Featuring a precision-machined stepped profile along the edge or surface, these optical windows allow seamless mechanical mounting, precise axial positioning, and reliable hermetic sealing without sacrificing clear aperture. Manufactured from high-purity material, they serve as ideal components for thermal imaging, medical IR devices, and industrial laser equipment.
