CO₂ Laser ZnSe Plano-Convex Lens

Focusing lenses are used to focus laser beam. The objective of focusing the laser beam is to concentrate the laser power for material processing. ZnSe Lenses are widely used for COlaser applications because of its low absorption at infrared wavelengths as well as its visible transmission.

Product Description

CO₂ Laser ZnSe Plano-Convex Lens

Eternal Optics manufactures precision CO₂ Laser ZnSe Plano-Convex Lenses designed for 10.6 μm CO₂ laser systems and infrared optical applications. Made from high-quality Zinc Selenide (ZnSe) material, these lenses provide excellent infrared transmission, low optical absorption, and reliable performance for laser focusing and beam delivery applications.

A ZnSe Plano-Convex Lens is a positive focal length lens commonly used to focus or collimate CO₂ laser beams. With a flat surface on one side and a curved surface on the other, the plano-convex design provides efficient focusing performance and is widely used in industrial laser systems, research equipment, and custom optical assemblies.

Our 10.6µm ZnSe Plano-Convex Lenses feature wavelength-specific AR (Anti-Reflective) coatings optimized for CO₂ laser applications, providing high transmission, reduced reflection loss, improved laser efficiency, and enhanced durability under high-power laser operation.
