Imaging reader and method with internal window reflections directed away from imager

A target is illuminated with illumination light for image capture by a solid-state imager of an imaging reader. Internal reflections of the illumination light at a window are minimized, if not eliminated, by configuring the window as a non-planar optical element operative for redirecting the interna...

description A target is illuminated with illumination light for image capture by a solid-state imager of an imaging reader. Internal reflections of the illumination light at a window are minimized, if not eliminated, by configuring the window as a non-planar optical element operative for redirecting the internal reflections away from the imager to enhance reader performance.
