a, c Focal spot profiles and normalized intensity profiles for various wavelengths. b, d Images of element 5 and 6 in group 5 on the 1951 United States Air Force resolution target formed by the achromatic metalens. Scale bar, 20 μm. e, f Schematic diagram of a 24-h imaging detection. The right embedded image is the visible and NIR imaging results, respectively. The left embedded image is the schematic diagram of incident light band.
