Abstract: An apparatus and method for imaging a target, includes a housing having a presentation area, a solid-state imaging sensor having an imaging array of image sensors looking at a field of view that extends through the presentation area to the target, and an imaging lens assembly for capturing return light over the field of view from the target through the presentation area, and for projecting the captured return light onto the imaging array during imaging of the target. The assembly has a plurality of lenses, an aperture stop, and a holder for holding the lenses and the aperture stop in spaced relation along an optical axis. The aperture stop has a non-rotationally symmetrical aperture through which the optical axis extends. Alignment elements on the imaging lens assembly are used to align the non-rotationally symmetrical aperture with the imaging array.

Abstract: Laser power control arrangements interrupt power to a laser used in electro-optical readers upon detection of operating conditions not conforming to preestablished standards, and adjust power to enhance reader performance without violating prevalent safety standards. Dual monitors are used to independently monitor the output power of the laser.
