Abstract
An optical lens assembly includes an optical lens and a Pancharatnam Berry Phase ('PBP') element coupled to the optical lens. The PBP element is configured to provide chromatic aberration correction for the optical lens. An Abbe number of the PBP element and an Abbe number of the optical lens have opposite signs.
