Abstract

See full text

A machine-readable symbol reader can include a housing, a window, an illumination source, a wedge-shaped optical element, and a sensor array. Illumination can be coupled into the optical element through a base surface of the optical element and out of the optical element through a leg surface of the optical element. Illumination beams coupled out of the optical element through the leg surface can be parallel or substantially parallel to one another, and can exit the machine-readable symbol reader at a grazing angle to illuminate a machine-readable symbol at a grazing angle.
