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