Detail Information

Standard & Multi-Spectral CVD Zinc Sulfide (ZnS) IR Dome Optical Lens

 
Felix Glass ZnS IR Dome Lens is a hemispherical spherical integrated optical protective lens, manufactured from high-purity CVD polycrystalline zinc sulfide crystal. We supply two mainstream versions: standard single long-wave infrared dome and multi-spectral visible-infrared dual-band dome, covering all outdoor infrared imaging equipment demands.
 
ZnS material features 0.4–14μm ultra-wide transmission range, higher hardness and superior moisture resistance compared with ZnSe crystal, greatly reducing oxidation and scratch risks in harsh rainy, dusty environments. The hemispherical dome structure acts as both sealing protective housing and weak focusing optical lens, effectively correcting infrared image distortion, and completely isolate internal infrared detector from dust, water vapor, sand and splash.
 
Custom multi-band AR anti-reflection coating and outer DLC hard protective coating can be deposited on inner and outer surfaces, improving infrared transmittance and further enhance surface wear resistance. Multi-spectral version supports simultaneous visible light auxiliary alignment and 8–14μm thermal imaging, while standard LWIR dome only transmits long-wave infrared to block visible stray light for pure thermal imaging effect.

 

Core Optical Specifications

 
- Raw Material: High purity CVD polycrystalline Zinc Sulfide (ZnS)
- Dome Shape: Full hemispherical spherical single-piece dome
- Two Optional Versions
1. Standard Dome: 8–14μm LWIR single infrared band, block visible light
2. Multi-Spectral Dome: 0.4–14μm visible + full infrared dual band transmission
- Optional Coating: AR anti-reflection coating + DLC hard protective composite coating
- Average Transmittance: >88% within target spectrum after AR coating
- Surface Quality: Standard 60-40 scratch-dig, upgradeable to aerospace grade 20-10
- Hardness & Stability: High hardness, moisture-proof, anti-oxidation, stable from -60℃ ~ +130℃
- Custom Parameter: Custom dome diameter, wall thickness, inner & outer curvature radii
 

Core Product Advantages

 
1. Two optional dome types: standard single LWIR for pure thermal imaging; multi-spectral dual-band for day-night dual-spectrum equipment
2. CVD ZnS higher hardness & moisture resistance than ZnSe, suitable for long-term outdoor all-weather operation
3. Integrated hemispherical dome combines protective shell and optical lens, simplify infrared module assembly structure
4. Dual AR+DLC composite coating optional, boost infrared transmittance and resist scratch, water vapor and oxidation
5. Factory direct supply, support large-diameter hemispherical forming, stable batch consistency for aerospace & vehicle bulk orders
6. Fully customizable size, curvature and coating spectrum to match UAV, vehicle night vision and aerospace infrared detection optical system drawings
 

Typical Application Scenarios

 
- Vehicle-mounted LWIR night vision thermal imaging cameras
- UAV airborne multi-spectral reconnaissance photoelectric pods
- Ship, mining outdoor all-weather infrared temperature monitoring equipment
- Security long-distance perimeter thermal detection surveillance cameras
- Aerospace infrared guidance & remote sensing detection optical assemblies
- Handheld portable thermal imager hemispherical protective housing
 

OEM Manufacturing Capability

 
We provide full one-stop CVD ZnS optical processing including large ZnS blank hot forming, ultra-precision hemispherical spherical polishing, multi-band AR+DLC composite coating, edge deburring, strict spectral transmittance testing and surface hardness inspection.
Prototype sampling, small-batch trial production and factory mass supply are supported. Every standard & multi-spectral ZnS infrared dome is fully tested to meet customer-specified spectral, dimensional and environmental stability requirements before delivery.
 

Standard FAQ

 
1. What is the difference between standard ZnS dome and multi-spectral ZnS dome?
Standard dome only transmits 8–14μm long-wave infrared and blocks visible light, for single thermal imaging; multi-spectral dome transmits visible light + full infrared, for day-night dual-spectrum detection equipment.
2. Why choose ZnS dome instead of ZnSe dome for outdoor equipment?
ZnS has higher hardness and excellent moisture oxidation resistance, not easy to scratch or oxidize under long-term outdoor rain and dust environment; ZnSe is soft and prone to surface damage without DLC coating.
3. Can I customize dome size and coating parameters for aerospace optical pods?
Yes, we support custom hemispherical diameter, wall thickness, curvature radii, and AR+DLC composite coating optimized for single LWIR or multi-spectral dual band.
4. What equipment matches this ZnS infrared dome lens?
It fits UAV airborne photoelectric pods, vehicle night vision thermal cameras, outdoor industrial infrared monitoring equipment and aerospace infrared remote sensing assemblies.
5. Do you provide factory mass supply for CVD ZnS infrared domes?
We offer factory direct bulk supply, small trial samples and OEM customization, all ZnS domes pass full spectral transmittance and environmental stability inspection before shipment.
