Abstract
A photoelectric sensor includes an emitter that emits a plurality of light beams. Fractions thereof pass through transparent portions of a first body and a second body in series before intersecting an optically powered surface, which directs the fractions to a target focusing an image that passes through a perimeter of the first body in one direction and focusing an image that passes through a perimeter of the second body in a perpendicular direction. The emitter, first and second bodies, and the optically powered surface are positioned so as to form a light spot on the target within which the fractions of the plurality of light beams substantially overlap. The fractions of the plurality of light beams reflect off of the target and are received by a receiver, which detects changes in the light to determine whether a mark is present on the target.
