Abstract

A retroreflective optical scan module, for example for in a bar code reader including a light source mounted on the base of the module and at least one fold mirror for reflecting and redirecting the scanning light beam along an optical path which is parallel to the base and over at least a portion of the top side surface of the module, so that the scanning beam is longer than the length of the side of the module which the scanning beam passes over enroute to the target.
