Product Family Description

Low Absorption and Low Scatter from 0.4 - 12μm
Higher Durability than Zinc Selenide
Ideal for Use with Infrared Sensors

ISP Optics Zinc Sulfide (ZnS) Windows feature low absorption and low scatter through the Visible (VIS) and Infrared (IR) spectrum from 0.4 - 12μm. Zinc Sulfide is a chemically vapor deposited (CVD) material which is commonly used in imaging systems featuring a visible and thermal path. Compared to Zinc Selenide (ZnSe), it is slightly harder and more chemically resistant. ISP Optics Zinc Sulfide (ZnS) Windows are ideal for systems that have both visible and mid-wave infrared (MWIR) or long-wave infrared (LWIR) sensors.
