Description :

Properly designed aspherical lenses fully compensate spherical aberrations. Aspherical lenses are effective in the elimination of not only spherical aberration, but also other forms of aberration generated by lenses. Aspherical lenses are also used to compensate for distortion aberration. Aspherical lens is produced by exactly cutting away some part of a spherical surface. A standard spherical lens has the undesirable property (called spherical aberration) of causing a stronger diffraction of light rays the further it is from the optical axis of the lens.
