1. A meta-optical device comprising:
a meta-lens comprising a plurality of nano-structures arranged in a two-layer structure;
a band pass filter configured to transmit light of predetermined wavelengths within an operation wavelength band of the meta-lens;
a spacer layer provided between the meta-lens and the band pass filter, the spacer layer supporting the plurality of nano-structures and providing a separation distance between the meta-lens and the band pass filter; and
a refractive lens having a flat surface and a curved surface, wherein the plurality of nano-structures are disposed on the flat surface of the refractive lens.
