The word "anamorphic" and its derivatives stem from the Greek words meaning formed again. Anamorphic prism pairs find its application where the profile of a beam is required to be altered or for changing the dimension of a beam in one dimension. This makes it ideal for converting the elliptical beam shape of laser diodes into a nearly circular one. Depending on the orientation of the prisms, the beam size may be either reduced or expanded and the amount of change is variable depending on the angular position of the prisms. The principle of beam shaping with anamorphic prism pairs is based on changes of the beam radius for refraction at flat prism interfaces. Anamorphic prisms can be purchased as single items, but also as mounted and properly aligned prism pairs, setups with rotatable mounts, where the prism orientations can be precisely realigned by the user.
