ZnSe & ZnS Infrared Window Manufacturer | CVD Zinc Selenide Zinc Sulfide IR Windows
Detail Information
Felix Glass Co., Limited is a professional manufacturer of CVD ZnSe and CVD ZnS infrared windows. Our IR windows are fabricated from high-purity chemical vapor deposited zinc selenide and zinc sulfide, delivering excellent transmittance across mid-wave and long-wave infrared bands. We offer plano windows, domed windows, blanks, and customized optical windows with DLC, AR, BBAR coatings, widely used for CO₂ laser optics, FLIR thermal imaging, infrared spectroscopy, security surveillance and aerospace optical systems. Common optical glass blocks infrared radiation and cannot be used for MWIR / LWIR transmission. CVD ZnSe and CVD ZnS are classic infrared substrate materials with low absorption in the infrared spectrum. ZnSe performs best for CO₂ laser (10.6μm) transmission; multispectral CVD ZnS works reliably over a broad IR range and offers superior mechanical strength and impact resistance. Precision polished ZnSe / ZnS windows suppress scattering and absorption loss, protecting internal infrared detector chips and laser resonators from dust, moisture and mechanical damage. ZnSe optimized for 10.6μm CO2 laser; Multispectral ZnS covers MWIR to LWIR for thermal imaging and multispectral optics. Custom diameter, thickness, chamfer, wedge, domed profile; DLC, AR, BBAR anti-reflection coatings for infrared wavelengths available. CVD ZnSe features excellent homogeneity and ultra-low absorption at 10.6μm, the preferred substrate for CO₂ laser cutting heads and laser resonators. Multispectral CVD ZnS has higher hardness and erosion resistance, suitable for harsh-environment thermal imaging windows and airborne IR domes. We supply uncoated windows, single-band AR, broadband BBAR and DLC hard carbon coating to improve scratch resistance and anti-reflection performance. Material selection depends on working wavelength, mechanical load and environmental exposure. ZnSe is the first choice for CO₂ laser transmission optics, while multispectral ZnS dominates rugged thermal imaging, surveillance and aerospace IR windows. ZnSe protective windows for laser cutting, engraving, welding heads, low absorption at 10.6μm infrared laser wavelength. MS ZnS infrared windows for mid-wave and long-wave thermal cameras, perimeter monitoring and handheld thermal imagers. High strength multispectral ZnS domes and windows for airborne, missile seeker and harsh-environment infrared optics. Confirm material (ZnSe / MS ZnS), dimension, surface specs, coating type, operating wavelength and environmental requirements. Select qualified CVD ZnSe or multispectral ZnS blanks, inspect raw transmission and internal inclusion level. CNC grinding, contour turning for flat, wedged or domed infrared window profiles. Ultra-precision polishing, followed by vacuum deposition of AR, BBAR or DLC protective coatings. FTIR transmission, surface figure and scratch-dig inspection; shockproof anti-scratch packaging for fragile IR optics. We support small batch prototype samples and large-volume serial manufacturing of CVD ZnSe and multispectral ZnS infrared windows. To get an accurate quotation, please specify substrate type, size, surface quality, coating requirement, quantity and working environment. ZnSe is softer and needs careful handling; MS ZnS offers better hardness and weather resistance for outdoor and airborne applications. Our infrared optical engineers can advise material and coating selection for your MWIR, LWIR or CO₂ laser project. Main working wavelength is 10.6μm CO₂ laser; priority is ultra-low absorption and excellent optical homogeneity. System covers broad IR bands, requires higher mechanical hardness, abrasion resistance and outdoor / airborne rugged use. The IR window faces dust, sand erosion, frequent cleaning or high abrasion risk; DLC greatly improves surface durability. CVD ZnSe infrared window is the standard protective window for CO₂ laser cutting heads, featuring very low absorption at 10.6 micron wavelength. Multispectral ZnS transmits from visible through long-wave infrared, harder than ZnSe, widely used for thermal imaging and aerospace IR domes. Yes, DLC hard coating is available, improving scratch and erosion resistance, commonly used for ZnS thermal imaging windows. ZnSe is relatively soft and sensitive to scratches; handle with care. Multispectral ZnS is much tougher for rugged environments. Yes, we can produce flat, wedged, rectangular and domed ZnS / ZnSe IR windows based on customer drawings. Tell us your target material (ZnSe or MS ZnS), dimension, coating, operating wavelength and order quantity. Felix Glass infrared optical team will evaluate manufacturability, transmission performance and issue formal quotation for customized CVD zinc selenide / zinc sulfide infrared windows.
