Compact hybrid imaging lens assembly in an imaging reader
摘要:
A compact hybrid imaging lens assembly captures return light from a target over a field of view of a linear array of image sensors of a solid-state imager, and projects the captured return light onto the array during electro-optical reading of the target. The assembly includes a plastic lens for optical aberration correction, a glass lens spaced away from the plastic lens along an optical axis, and an aperture stop between the lenses and having an asymmetrical aperture through which the optical axis extends. The glass lens has substantially all the optical power of the imaging lens assembly for thermal stability, and the plastic lens has substantially no optical power. A holder holds the lenses and the aperture stop away from the array. Alignment elements on the plastic lens align the asymmetrical aperture relative to the linear array.
