ZnSe Plano Convex Lens
Description
ZnSe Plano Convex Lenses are precision infrared optical components manufactured from Zinc Selenide (ZnSe). Featuring one flat surface and one convex surface, these positive lenses are designed for focusing, collimating, and collecting infrared radiation in laser and imaging systems.
With its broad infrared transmission range, ZnSe is well suited for CO₂ laser optics, thermal imaging systems, LWIR optics, infrared sensors, and other infrared optical applications. The plano-convex configuration provides an efficient solution for optical systems requiring a positive focal length and controlled infrared beam focusing.
ElyonOptics supplies custom ZnSe Plano Convex Lenses according to optical drawings, technical specifications, and application requirements. Different diameters, focal lengths, thicknesses, surface specifications, and anti-reflection coatings are available for prototype and volume production.
