Aspheric lens

An aspheric lens is a type of optical lens that has a surface shape designed specifically to reduce distortions and improve image quality. Unlike traditional spherical lenses with a simple rounded surface, aspheric lenses have complex curves that allow them to focus light more accurately. This results in sharper images, fewer distortions, and better performance in applications like cameras, glasses, and microscopes. Because they can correct aberrations more effectively, aspheric lenses often enable thinner, lighter designs while maintaining high optical quality.
