... Here, we show that the artificial dispersion of a single metasurface can be used to correct spherical and chromatic aberrations of refractive lenses. ...
As examples, we designed and fabricated a metasurface aberration corrector (hereafter referred to as a metacorrector) that renders a commercial spherical lens achromatic and diffraction-limited across the visible. ...

Noch handelt es sich (leider) nicht um eine Oberflächenveredelung, sondern um einen experimentellen Aufbau (sorry fürs teasern
