Recently, developments in meta-surfaces have allowed for the possibility of a fundamental shift in lens manufacturing from the century-old grinding technology to nanofabrication opening a way toward mass producible high-end meta-lenses. Inspired by early camera lenses and to overcome the aberrations of planar single-layered meta-lenses, we demonstrate a compact meta lens doublet by patterning two metasurfaces on both sides of a substrate. This meta-lens doublet has a numerical aperture of 0.44, a focal length of 342.5 mu m, and a field of view of 50 that enables diffraction-limited monochromatic imaging along the focal plane at a wavelength of 532 mu. The compact design has various imaging applications in microscopy, machine vision, and computer vision.
