Optical ZnSe Zinc Selenide Plano Convex Focusing Lens for Laser
Description
Zinc selenide is a commonly used optical glass material in the infrared band with a transmission band of 600nm-16μm. It has low absorption and thermal shock resistance, and is commonly used in thermal imaging systems, as well as in some visible optical systems, and can be used as a substrate for a variety of optical components. Zinc selenide (ZnSe) plano-convex (PCX) lenses are mainly used for focusing or collimating applications in the mid-wave and long-wave infrared spectra. ZnSe PCX lenses focus light into a single point and are commonly used for aiming and focusing monochromatic light sources.

Frequently Asked Questions
ZnSe offers high transmittance (＞70%) in the mid-infrared range (8–12 μm), making it ideal for systems like CO₂ lasers and thermal imaging.
Unlike Ge or Si, ZnSe has lower absorption and better thermal stability under high-power laser exposure, reducing thermal lensing effects.
