Abstract
A method and apparatus for anamorphically shaping a beam of radiation and for deflecting such beam by 90.degree. independently of beam wavelength shifts within a predetermined wavelength range. The apparatus of the invention comprises an achromatic prism comprising a pair of prism elements of different optical materials. The prism elements are joined together to define a complex prism having four faces which interact with an incident beam to achieve a desired beam shaping and deflection. Two of such faces are parallel, one face being in a plane parallel to the direction of propagation of an incident beam, and the other being in a plane perpendicular to the beam exiting the prism.
