Polymer Aspheric Lens or Aspheric Lens is a Lens whose surface profiles are not portions of a sphere or cylinder. The Asphere's more complex surface profile can reduce or eliminate spherical aberration and also reduce other optical aberrations...
Aspheric Lenses have complex curved surfaces, such as where the radius of curvature changes according to distance from the optical axis. Spherical lenses are subject to various aberrations and therefore cannot concentrate all the light into one...
