From: On-chip integration of achromatic metalens arrays

Fig. 5

a The top-view optical microscope images of the metalens array. b The high-resolution top-view optical microscope images of single metalens. c–e are the measured averaged focusing efficiencies, focal lengths and numerical aperture for 25 separated single metalenses. f The raw light-field image with the achromatic metalens array. g The rendered images with color distortion and background subtraction. (1–4) represent different positions with different magnification rates of the original image respectively.
