1. A graphical code reader comprising:

  • control circuitry for the graphical code reader;

    a multi-functional optical element in electronic communication with the control circuitry, the multi-functional optical element comprising;

    a support structure;

    a monolithic imaging lens and target generating mechanism operably connected to the support structure, wherein the imaging lens and target generating mechanism includes a lens and targeting structures for generating converging offset beams to feedback proper target distance;

    targeting light sources positioned by the support structure such that light from the targeting light sources is directed through the targeting structures to generate the converging offset beams;

    an imaging board connected to the support structure; and

    an imager mounted to the imaging board and positioned to obtain an image from the lens.
