A light source 10 illuminates an original on a platen 11. One set of rays P1 is reflected from one half of the beam splitter 12 to focus at point A and a second set of rays P2 is reflected from the other half of beam splitter 12 to focus at point B. The beam splitter is two mirror surfaces which are formed on a single substrate, resulting in a beam splitter which produces both images at 100% efficiency, needs no alignment and has good mechanical and temperature characteristics.
