The Maksutov Cassegrain is a catadioptric design similar to the SCT but with a different optical component that corrects for lower order spherical aberration. In a typical Maksutov Cassegrain the primary mirror is concave with a spherical curvature to the surface and with a very short focal ratio similar to that in a modern Schmidt Cassegrain.

Parallel rays of light reflected from a convex spherical mirror (small in size compared with its radius of curvature) seem to originate from a well-defined focal point at the focal distance f behind the mirror. Convex mirrors diverge light rays and thus have a negative focal length. Ray tracing is as useful for mirrors as for lenses.

Get PriceEffects of glistenings in intraocular lenses
Glistenings consist of multiple microvacuoles in intraocular lenses (IOLs) that cause retinal stray light and may affect quality of vision. For four IOL types the microvacuole particle size distribution and particle volume density was measured using confocal light microscopy and dark field microscopy and the corresponding extinction coefficient γ was determined.

A Klieg light is an intense carbon arc lamp especially used in filmmaking. It is named after inventor John Kliegl and his brother Anton Kliegl. Klieg lights usually have a Fresnel lens with a spherical reflector or an ellipsoidal reflector with a lens train containing two plano-convex lenses or a single step lens.

The process of anamorphosing optics was developed by Henri Chrétien during World War I to provide a wide angle viewer for military tanks. Up to the early 1960s three major methods of anamorphosing the image were used: counter-rotated prisms (e.g. Ultra Panavision) curved mirrors in combination with the principle of Total Internal Reflection (e.g. Technirama) and cylindrical lenses (lenses ...
