Paper Abstract

In our paper we show the exact (not zero thickness) equation of the finite thickness waveguide Fresnel lenses. We calculate the RMS wavefront distortion caused by the zero thickness approximation of the lens shape. We propose new type large numerical aperture hybrid lenses. These consist of refractive and dijractive (analogue Fresnel) sections. These lenses can be realised by optical lithography, because the dimension of the Fresnel zones can be varied in accordance with the capabilities of the lithographic equipment.
