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 |

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.
