Abstract

A lens assembly is positioned between an illuminated scanning area and a detector. A multiple reflecting assembly positioned between the lens assembly and the illuminated scanning area defines a folded light path between the lens assembly and the illuminated scanning area. A prismic reflecting assembly is movably mounted between the lens assembly and the multiple reflecting assembly, so that the length and direction of the folded light path can be changed by moving the prismic reflecting assembly to align and focus the image of the illuminated scanning area on the surface of the detector.
