Abstract
The optical imaging apparatus includes a metasurface lens including a substrate and a plurality of nano-structures patterned on a first side of the substrate. The optical imaging apparatus further includes imaging optics disposed in a spaced apart relationship with a second side of the substrate. The second side is opposite the first side on which the nano-structures are patterned. A surface of the imaging optics and the second side of the substrate define a space for accommodating an immersion fluid. The metasurface lens is configured to direct light incident on the plurality of nano-structures towards the imaging optics through the space accommodating the immersion fluid.
