  • Parabolic-Cylindrical Lenses
  • Plano-Parabolic Lenses
  • Bi-Parabolic Lenses
  • Technically, an aspherical lens is a lens whose curved surface does not conform to the shape of a sphere; an aspherical lens is used in correcting distortion in ultra-wideangle lenses or coma in large-aperture lenses brought about by spherical aberration. A aspherical lens element or two can substitute a bigger number of spherical lens elements to achieve similar or better optical results and to reduce the overall cost of production and more compact of the size of a lens - especially in the case of zoom lenses, where lens elements of more than 10 are common.
