What are ZnS Infrared Windows?

ZnS infrared windows are common infrared optical components made by Zinc Sulfide.

People also choosed them in infrared imaging, infrared detection and laser systems.

It has an excellent infrared transmission range of 8 to 14 micrometers. The window has a wide transmission range, making it an excellent material for thermal imaging.

It is highly suitable for applications that require both visible and infrared.

Introduction of ZnS

Zinc sulfide (ZnS) is an important inorganic compound and a commonly used functional material in the fields of optics and electronics.

It possesses excellent chemical stability and mechanical strength. In terms of optics, it has a wide transmission range, with high transmittance from visible light to the infrared band.

ZnS is widely used in infrared window plates, lenses, and optical enclosures. In lighting and electronic devices, ZnS is also often used as a fluorescent powder and semiconductor material.

Therefore, it has important applications in infrared imaging, laser systems, night vision equipment, aerospace and military industries.

Chengyu customizes square/rectangular zinc sulfide windows, and they are equipped with additional coatings and designs.
