An optical hybrid lens (100) comprises a substrate (300) having a first surface (301) and a second surface (302) opposite the first surface (301). A sub-wavelength grating lens (200) is disposed on the first surface (301) and comprises a plurality of posts (210, 211, 212, 213, 215, 216). The plurality of posts (210, 211, 212, 213, 215, 216) is arranged on the first surface (301) and the posts extend from the first surface (301). A refractive lens (400) is arranged on the sub-wavelength grating lens (200) at least partly enclosing the plurality of posts (210, 211, 212, 213, 215, 216). Alternatively, the refractive lens (400) is arranged on the second surface (302). |
