1. An evaluation apparatus for digital data gathering devices that can ensure uniform evaluation results from two or more of said digital data gathering devices, said digital data gathering devices accepting incoming light through a lens, said evaluation apparatus comprising:

  • a light shroud having an enclosing wall, said enclosing wall substantially surrounding said lens and extending a predetermined distance outwardly therefrom and defining a distal edge portion;

    an illumination source in selective communication with an interior of said light shroud thereby preventing ambient light from entering said interior of said light shroud when a substantial entirety of said distal edge portion of said enclosing wall is in touching contact with an object;

    a calibration device arranged within said light shroud, said calibration device selectively reflecting light from said illumination source; and

    wherein said evaluation apparatus alters subsequent digital data gathering by said evaluation device in dependence upon said reflected light, thereby ensuring said uniform evaluation results from any of said digital data gathering devices having said calibration device.
