An optical system is disclosed which enables easy conversion of a xerographic copier/duplicator from size-to-size imaging to reduction imaging. In the figure, 1' represents a platen upon which the document to be reproduced is placed, 2 represents the photoreceptor maintained in flat configuration, and 3s represents the lens in position for size-to-size imaging with full-frame flash exposure, while mirrors 4', 5' provide for optical path geometry and for image reversal main-tenance. In order to accomplish reduction imaging upon the photoreceptor held in the same position, platen 1' is moved to position 1, while lens and mirror unit 3', 4', 5' is moved to positions 3, 4, and 5, respectively. The transition for the lens-mirror unit is accomplished without any changes whatsoever in the relative geometry of the three elements.
