A method and apparatus for anamorphically shaping a beam of radiation and for deflecting such beam by 90.degree.. The apparatus consists of a prism having at least four faces, two of such faces being parallel. The prism is arranged to receive a beam at the Brewster angle .THETA..sub.B, and is adapted to deflect the beam by 90.degree. by refraction and double internal reflection. The prism faces define four internal angles of .THETA..sub.B, 90.degree.+.THETA..sub.B, 90.degree.-.THETA..sub.B and 180.degree.-.THETA..sub.B.
