Abstract : The patent describes a wide angle anamorphic refractive lens system having an anamorphic field of view in excess of 160 degrees x 60 degrees which can be scaled for T.V. camera and Eidophor projection. The system is characterized by a large diameter negative group of lens elements in which all elements have spherical surfaces except one element which has cylindrical surfaces, and a positive group including an element having at least one cylindrical surface which brings an image, compressed in one direction by the cylindrical element of the first group, into sharp focus.
