ABSTRACT:
Apparatus for enabling an electrophotographic reproduction device to make reproductions of slide transparencies. The electrophotographic reproduction device includes a transparent platen for supporting information to be reproduced. A main lens assembly projects a focused image of information on the transparent platen onto a photoconductive member to form a latent image charge pattern of such information. The apparatus for enabling the electrophotographic reproduction device to make reproductions of slide transparencies comprises a mechanism for projecting a real image of a slide transparency along an optical path onto the transparent platen. A Fresnel lens, serving as a field lens for the main lens assembly, is located in the optical path of the projecting mechanism, between the projecting mechanism and the transparent platen, and space from the transparent platen so as to be beyond the depth of focus of the main lens assembly.
