Product Description

Aspheric Lens

The surface profiles of aspheric lenses are not a portion of a sphere or cylinder. Their curvature radius varies with the central axis. Aspheric lenses have unique advantages over spherical lenses. For example, they can improve optical quality, reduce optical components and design costs. They are widely used in optical instruments, images and optoelectronics industries, such as digital cameras, CD players and high-end microscopic instruments.

A sphere is defined by a single radius of curvature. Aspheric Lens have at least one aspherical surface. Optical engineers generally think of aspheric surfaces as aspheric, rotationally symmetric surfaces. The radius of curvature of the aspheric surface varies gradually from the center of the lens to the edge.
