PICTURE MODULE, READER AND METHOD FOR LIGHTING AND PICTURE OF OBJECTIVES WHICH SHOULD BE READ OVER AN EXTENDED FIELD OF WORK DISTANCE

摘要

Targets that are to be read by image capture are illuminated and mapped over an extended range of working distances. A close-up image receives returning light over a relatively wide field of view field from a target located in a near field of the region. A telephoto takes in returning light over a relatively narrow field of view field from a target located in a far field of the area. A single illumination light assembly is shared by both the near and far images. An illumination light source emits illumination light, and an illumination lens assembly optically modifies the emitted illumination light and simultaneously illuminates a wide illumination field to illuminate the target located in the near field of the region and a narrow illumination field to illuminate the target in the far field of the area is arranged.
