Abstract
A graphical code reader is disclosed. The graphical code reader includes control circuitry for the graphical code reader and a multi-functional optical element in electronic communication with the control circuitry. The multi-functional optical element includes a support structure and a monolithic imaging lens and target generating mechanism operably connected to the support structure. The imaging lens and target generating mechanism includes a lens and targeting structures for generating converging offset beams to feedback proper target distance. Laser diodes are positioned by the support structure such that laser light from the diodes is directed through the targeting structures to generate the converging offset beams. An imaging board is connected to the support structure. An imager is mounted to the imaging board and positioned to obtain an image from the lens.
