Product Description

Product Description

Zinc Sulfide (ZnS) Windows are essential infrared optical components, valued for their superior optical and physical properties across various applications.

Material Composition:Made from zinc sulfide (ZnS) single crystal or polycrystalline materials, including Optical ZnS and Chemically Vapor Deposited (CVD) ZnS (also known as ZnS-Single Crystal).

Optical Properties

Broadband Transmission:

High transmittance in the wavelength range of 0.4~12 μm, with excellent performance in the mid-infrared (3~12 μm) region, suitable for infrared applications like thermal imaging and laser systems.

Low Refractive Index:

Refractive index of ~2.2 at 10.6 μm, further optimized by anti-reflective coatings for higher transmission efficiency.
