Paper Abstract

In some white-light imaging applications it is desirable to make the optical elements extremely thin. Numerous practical advantages are derived if the lenses are one to two orders of magnitude thinner than conventional refractive lenses. For example, these lens systems provide minimal weight and compactness, and are potentially low cost. Although diffractive lenses are only a few microns thick, they have severe chromatic aberrations. Approaches are compared for making the lenses thinner and techniques are examined for correcting chromatic aberrations. There are basic limits to the polychromatic MTF and chromatic correction that can be achieved.
