An imaging reader for, and a method of, electro-optically reading a symbol by image capture employ an illuminating assembly that includes a laser for directing an illuminating laser beam along a path to the symbol to illuminate the symbol during image capture, a diffusing assembly that includes a movable diffuser in the path of the illuminating laser beam to diffuse the illuminating laser beam as diffused illuminating laser light, and a solid-state imager that includes an array of image sensors for capturing the diffused illuminating laser light returned from the symbol in a range of working distances over a field of view.
