Patent ID: 8657194

Claim:
A compact hybrid imaging lens assembly for capturing return light from a target over a field of view of an array of image sensors of a solid-state imager, and for projecting the captured return light onto the array during electro-optical reading of the target, the assembly comprising: a plastic lens for optical aberration correction; a glass lens spaced away from the plastic lens along an optical axis, the glass lens having substantially all optical power of the imaging lens assembly for thermal stability; an aperture stop between the lenses and having opaque walls bounding an asymmetrical aperture through which the optical axis extends; a holder for holding the lenses and the aperture stop in spaced relation relative to the array; and alignment elements remote from the holder for aligning the asymmetrical aperture relative to the array, wherein the alignment elements include a plurality of projections and a plurality of cutouts, each projection being received in a respective cutout; and wherein one of the aperture stop and the plastic lens has the cutouts, and wherein the other of the aperture stop and the plastic lens has the projections that are received in the cutouts to align the aperture stop with the plastic lens.
