1. A reader for electro-optically reading a target, comprising: a) a housing having a window; and b) a solid-state imager in the housing and including an array of image sensors for capturing target light through the window from the target over a field of view; c) an illuminator in the housing for directing illumination light to and through the window to illuminate the target during reading, a portion of the illumination light incident on the window being reflected therefrom into the housing away from the window; and d) the window being configured as a non-planar optical element for redirecting the reflected portion of the illumination light away from the imager to enhance reader performance.
