Abstract

An imaging system comprising a source of light movable with respect to an image carrier element and projectable thereon to generate an image, and an auto-focusing system for focusing the image-generating light source. The auto-focus system includes a second beam of light of a wavelength selected not to be actinic with respect to the image carrier element. The initial set up of the auto-focus system is enhanced by the use of the focusing system and a sensor for indicating the output of the focus photodetector to register a zero output which indicates the initial set position.
