Abstract
A right-angle optical prism is used to anamorphically shape and deflect by 90.degree. a beam of electromagnetic radiation. Preferably, one of the prism's acute angles is cut at Brewster's angle, and the prism is oriented in the optical path of the beam such that the beam (a) intercepts, at the Brewster angle, that prism face opposite the prism's Brewster angle, (b) is internally reflected by that prism face opposite the prism's other acute angle, and (c) intercepts the prism's hypotenuse face at 90.degree..
