    Abstract: A bioptics bar code reader has first (1) and second (2) windows disposed at an angle to each other, a first imager (3) for the first window (1) and a second imager (4) for the second window (2) and first and second optics for directing light from a bar code in a reading area between the windows to the first and second imagers. The two imagers each obtain an image of the bar code in the reading area.
