ABSTRACT:
A single optical fiber is placed at or near the nadir of the curvilinear section of the optical surface of a light emitting device. The LED element illuminates the bar code characters on the surface of the object being read, and the reflected light is transmitted up the optical fiber to a sensory means or the like. The elements are encased in an optical plastic medium for strength and durability, and resistance to environmental extremes.
