Product Description

Product Description:Zinc Selenide (ZnSe) Plano Convex (PCX) Lenses are plano-convex lenses based on zinc selenide. Zinc selenide is a commonly used optical glass material in the infrared band. The transmission band is 600nm-16μm. It has the characteristics of low absorption and thermal shock resistance. It is often used in thermal imaging systems and can also be used in some visible light optical systems. As a substrate for a variety of optical components.

A zinc selenide plano-convex lens focuses light into a point. Its characteristic is that the focal length is positive, one side is flat, and the other side is convex. Commonly used for aiming and focusing of monochromatic light sources. When in use, face the convex surface towards the incident light. Zinc Selenide Plano-Convex Lenses in combination with other lenses can be used for different applications such as beam shaping, beam collimation, beam expansion, and beam reduction. It is important to note that zinc selenide is a toxic material, please wear gloves when using it, and wash your hands after use.
