Tartalmi leírás:
Aberration-free flat lenses can be created by introducing phase discontinuities with hyperboloidal distribution on a metasurface. These lenses are able to focus light without aberration under axial illumination but suffer from serious aberration in case of oblique incidence. Here we introduce a simple design including an aperture stop and a flat lens with a modified phase distribution that has negligible aberration for incident angles in the range of -40° to 40°. With this design diffraction limited imaging systems can be created for a wide incident angle range without the need of complex lens systems.
