Abstract

Described is phased metalens depth of focus increase for camera focusing. An objective camera lens is configured to provide a focus window across multiple radial zones within a field of view. A camera imager is configured to capture an image of the field of view. When at least two of the radial zones have different back focal lengths relative the imager and the objective lens, a phased metalens is positioned between the objective lens and the camera imager. The metalens is configured to compensate for defocus caused by the different back focal lengths by increasing, across the radial zones within the field of view, a depth of the focus window. The metalens improves focus across the field of view, which prevents variations in objective lens characteristics from reducing image quality.
