Plano Convex Aspheric Lens
Plano convex aspheric lenses feature one flat surface and one convex aspheric surface. The controlled profile reduces spherical aberration, improves focusing and collimation, and can enable compact optical systems with fewer lens elements.
Plano Convex Aspheric Lens Overview
Plano convex aspheric lenses are precision optical components with one plano surface and one convex aspheric surface.
Unlike a conventional spherical singlet, the aspheric profile provides additional ray control to reduce spherical aberration and improve focusing, collimation or imaging performance.
Chenyu Optics manufactures custom designs in optical glass, fused silica and optical plastic with customized diameter, focal length, aspheric prescription, center thickness and coating.
Key Advantages of Plano Convex Aspheric Lens
