ABSTRACT:
A simplified optical arrangement for an electrophotographic copier for making multicolor reproductions of a multicolor original document. The copier includes at least one charged photoconductive member which is exposed by primary color separation images of an original document to form corresponding latent image charge patterns. The primary color separation images are projected onto the photoconductive member by the simplified optical arrangement which includes a catadioptric lens assembly optically located between the original document and the photoconductive member. The lens assembly includes relatively tilted dichroic mirrors spectrally sensitive respectively to the primary colors to separate an image of an original document into primary color separation images, and project such images respectively in straight line optical paths toward distinct spacial locations on the photoconductive member.
