25mm Diameter Uncoated Zinc Sulfide Multispectral lens

ZnS substrates could be made as ZnS infrared optics lens, ZnS aspherica lens, bi convex aspherical lens, ZnS optical round window and other ZnS elements. They are widely used in various high technology project and optical products.

Multi-spectral grade of zinc sulfide has low absorption and scatter properties over its broad transmission range of 0.4 - 12μm. Zinc Sulfide Multispectral is a chemically vapor deposited material which is commonly used in thermal imaging. With its excellent transmission properties in the visible and infrared, Zinc Sulfide Multispectral is the material of choice for systems that have both visible and mid-wave or long-wave infrared sensors. It is slightly harder and more chemically resistant than zinc selenide.
