WebSpherical aberration is the zonal variation of focus and it costs money and effort to control in an optical system. It is typically minimized through lens bending or using multiple spherical components or eliminat- ed by aspheres for an added cost. Spherical aberration can be eliminated by making lenses with an aspheric surface. Descartes showed that lenses whose surfaces are well-chosen Cartesian ovals (revolved around the central symmetry axis) can perfectly image light from a point on the axis or from infinity in the direction of the axis. See more In optics, spherical aberration (SA) is a type of aberration found in optical systems that have elements with spherical surfaces. Lenses and curved mirrors are prime examples, because this shape is easier to manufacture.
