  Metalenses, featuring ultra-compactness and CMOS compatibility, are limited
by the compromise between the diameter, numerical aperture, and working
waveband. To address this problem, we propose and numerically demonstrate a
centimeter-scale metasurface-refractive hybrid metalens working in the band of
440 - 700 nm. Revisiting the general Snell law, we present the phase profile of
a chromatic aberration correction metasurface that can apply to a plano-convex
refractive lens of an arbitrary surface type. Simulated by our semi-vector
method, the designed achromatic hybrid metalens achieves 81% chromatic
aberration suppression and polarization insensitivity. Broadband imaging
results of the hybrid metalens are further provided, verifying the achromatism
of the designed hybrid metalens. It can find applications in camera lenses and
other optical systems that need compact, high-performance lenses.
