A focusing device with respect to light of a predetermined wavelength band, the focusing device comprising:
- a substrate;
- a first thin lens provided at a first surface of the substrate and comprising a plurality of first scatterers;
- and
- a second thin lens provided at a second surface of the substrate and comprising a plurality of second scatterers,
- wherein the plurality of first scatterers of the first thin lens are configured to correct geometric aberration of the second thin lens, and
- wherein at least two of the plurality of second scatterers have different heights from each other.
