Aspheric Optics

II-VI Optical Systems provides aspheric lenses and mirrors manufactured using a wide variety of substrate materials.  The performance of standard spherical lenses and mirrors is limited due to inherent spherical aberration.  Aspheres are used when the application demands more perfect image formation or tighter focusing than is possible with spherical surfaces.  Often, a single aspheric surface is used to provide the function of several spherical surfaces.
