Anamorphic Prisms

Product Description

Hobbite® Precision Optics (Anamorphic Prisms)

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.

  • 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.
