An imaging scanner includes an illumination light source and a hybrid illumination lens. The hybrid illumination lens includes a first Fresnel surface facing the illumination light source and a second surface having a microlens array thereon. The first Fresnel surface is configured to direct light received from the illumination light source towards the second surface to generate illumination light towards a target object through the microlens array on the second surface.
