Abstract
Targets to be read by image capture are illuminated and imaged over an extended range of working distances. A near imager captures return light over a relatively wide imaging field of view from a target located in a close-in region of the range. A far imager captures return light over a relatively narrow imaging field of view from a target located in a far-out region of the range. A single illuminating light assembly is shared by both the near and far imagers. An illumination light source emits illumination light, and an illuminating lens assembly optically modifies the emitted illumination light, and simultaneously illuminates a wide illumination field to illuminate the target located in the close-in region of the range, and a narrow illumination field to illuminate the target located in the far-out region of the range.
