Home > Prisms > 14AP - Anamorphic Prisms
A pair of prisms can be designed into a much more compact package than a telescope using cylindrical optics
The ability of adjusting the position of the prisms allows the user to compensate for variations from one light source to another
The prisms are more cost effective than cylindrical lenses of comparable quality
Mount for anamorphic prisms is available upon request

Anamorphic prisms are used to change the dimension of a beam in one axis, the effect being analogous to that of a cylindrical lens. These two prisms can expand or contract the beam in one direction without any changes in the other direction. By adjusting the angles among the incident beam and two prisms, the shape of the beam can be changed. It is very easy to turn elliptical beam into circular beam. If beam shaping is required, a system using a pair of anamorphic prisms has several significant benefits.
