Illumination apparatus for optical readers
 An apparatus for illuminating an indicia in a sensing region of an object plane. A housing has a median longitudinal vertical plane and a horizontal scanning plane. A reflector for reflecting light directed thereagainst toward the sensing region has a first approximately curvilinear profile in a plane parallel to the scanning plane, and a second approximately curvilinear profile in a plane parallel to the median longitudinal plane. The central portion of the reflector defines an opening whereby light from the sensing may return in generally the same plane as light directed toward the sensing region.
