Aspheric lenses are characterized by at least one surface having a more complex shape slightly divergent from spherical (e.g. ellipse, parabole, hyperbole). Thanks to this property, use of these lenses allows for the spherical aberration of an image to be fully compensated resulting in an overall better quality image and more detail further from the optical axis. Moreover, one aspheric lens can replace a multi-lens system for the same results. Because of that, aspheric lenses are most often found in multi-component optical setups to ensure the desired quality of an image is met without unnecessary expansion in size.
Solaris Optics is able to make mild aspheres from flat or spherical surfaces up to about 10-15μm using corrective polishing (MRF) technology.
