    Large field-of-view (FOV) lens is an essential component in imaging systems. To realize the large FOV, conventional optics requires the combination of multiple lenses into a lens group to correct the aberration caused by different angles of incident light. In this paper, a near-infrared metalens is designed and fabricated, which consists of a single-layer metasurface and a metal aperture distributed on both sides of the substrate. The device can suppress aberration effectively and realize a 120° large FOV imaging at the wavelength of 940 nm. Experiments have demonstrated that the fabricated device exhibits good focusing performance within the designed FOV range, with an average experimental focusing efficiency of 45%.
