Zinc Selenide Optical Windows
Zinc Selenide (ZnSe) optical windows are infrared-transmitting components used in CO₂ laser systems, thermal imaging, spectroscopy and MWIR/LWIR optical equipment. Chenyu Optics manufactures custom ZnSe windows with controlled dimensions, thickness, flatness, parallelism, surface quality and wavelength-specific AR coatings.
Zinc Selenide Optical Window Overview
Zinc Selenide optical windows provide infrared transmission while protecting sensitive detectors, laser assemblies and imaging systems from the external environment.
CVD ZnSe is commonly selected for MWIR and LWIR equipment and for 10.6 μm CO₂ laser systems. Material thickness, surface finish and coating design are reviewed according to the operating band, incident power and service environment.
Chenyu Optics manufactures custom round, square and drawing-defined ZnSe windows with specified dimensions, thickness, flatness, parallelism, surface quality, edge treatment and infrared AR coating.
Key Advantages of Zinc Selenide Optical Window
