Zinc Sulfide Dome

Zinc Sulfide Dome is mainly used in infrared thermal imaging, laser systems, aerospace, and industrial inspection.
In infrared imaging and detection, it is primarily used as an optical window and sensor protective cover for thermal imaging systems in the 8–12 μm band and night vision devices.
In laser systems, aerospace, and industrial inspection, it is mainly used as observation windows and transmission windows.

Both ZnS Dome and ZnSe Dome are commonly used optical dome materials for infrared systems, but they differ significantly in spectral range, mechanical strength, transmission performance, and application scenarios.
ZnS is superior to ZnSe in spectral transmission range, mechanical properties, and thermal performance.
In applications, ZnS is more robust and suitable for multispectral systems, while ZnSe has better infrared transmission and is suitable for high-performance mid-infrared systems.

We mainly use Chemical Vapor Deposition (CVD) to produce ZnS or MS-ZnS blanks with high optical uniformity. During processing, precision grinding, polishing, ultrasonic cleaning, inspection, and diamond turning are applied.

Currently, we can customize according to customer requirements to ensure perfect compatibility with the system’s mechanical interface. Custom options include chamfer or bevel designs, adding flanges or bases for direct fixing or connection to equipment, designing structures with high concentricity and locating grooves, and machining holes or threads at specific positions.

Common coating options include broadband antireflection coatings, single-wavelength AR coatings, DLC diamond-like coatings, and reflective coatings.
