What is ZnS a prism?

ZnS prisms are optical components made by zinc sulfide optical crystal ,which are often used in optical application such as refration, reflection.

Zinc Sulfide is a high-quality optical material. It offers exceptional purity, high optical transmission, and outstanding mechanical durability.

The prism has a broad transmission range from 0.4 μm to 12 μm.

If you require performance across multiple wavelength bands, you can choose the ZnS prism for your requirments.

 

Why Use Zinc Sulfide for Prisms?

It offers unique optical advantages due to the features of Zinc Sulfide :

  • Broadband Transmission

Zinc sulfide has a high transmittance range from visible light to far infrared (0.4 μm – 12 μm), which is not only suitable for infrared imaging but also applicable to multi-band optical systems.

  • High Refractive Index

Around 2.2 at 10 μm, enabling compact prism designs with strong light bending ability.

  • Mechanical Durability

Resistant to scratches, impact, and harsh environmental conditions.

  • Thermal Stability

The ZnS prism can maintain performance over wide temperature ranges.

  • Low Scattering and Absorption

The prism can ensure the image more clear. And ot makes minimal signal loss.

 

Applications of the ZnS Prism

The ZnS prism has a various range of applications:

  • Infrared Imaging Systems

  • Spectroscopy

  • Aerospace & Defense

  • Industrial Machine Vision

 

How to handle the ZnS prism?

People should avoid using hands to touch the prism.

And it should be avoided Abrasive Materials. Because ZnS can be scratched by hard particles.

People also can choose AR coating or other coating if needed.

And also the prism surfaces are ensured to be polished to meet the required flatness and surface accuracy.

Please make sure to use the prism strictly in accordance with the instructions when using it.
