A wide angle, athermalized, achromatic, hybrid imaging lens assembly captures return light from a target over a field of view, and projects the captured return light onto an array of image sensors of a solid-state imager during electro-optical reading of the target. The assembly includes a plastic lens group for optical aberration compensation, a glass lens group spaced away from the plastic lens group along an optical axis, and an aperture stop between the lens groups and having an aperture through which the optical axis extends. The glass lens group has substantially all the optical power of the imaging lens assembly for thermal stability, and the plastic lens group has substantially no optical power. A holder holds the lenses and the aperture stop in front of the array.
