Aspheric Lens

An aspheric lens or asphere is a lens whose surfaces have a profile that is neither a portion of a sphere nor of a circular cylinder.


A single aspheric lens can often replace a much more complex multi-lens system. The resulting device is smaller and lighter, and possibly cheaper than the multi-lens design.


Small glass or plastic aspheric lenses can be made by molding, which allows cheap mass production. Due to their low cost and good performance, molded aspheres are commonly used in inexpensive consumer cameras, camera phones, and CD players.

Steep Aspheric lens surfaces produce large angles of refraction and hence short focal lengths. Aspheric lens surfaces can also be free from spherical aberration. For these reasons aspheric lenses produce highly efficient low f/number. They can be used to collimate or focus a lamp output or to collect radiation from a distant point.
