Abstract
A telephoto lens assembly including a primary lens sub-assembly having at least one lens, and being operable to collect and focus light to an intermediate focal location. The assembly further includes a secondary lens sub-assembly having at least one refractive lens, and being operable to collect and focus light from the primary lens sub-assembly. The lens assembly also includes a metacorrector positioned relative to the secondary lens sub-assembly and being responsive to the focused light from the secondary lens sub-assembly, where the metacorrector includes a meta-structure that is configured to correct aberrations in the light, provide focusing/defocusing power and/or to remove residual secondary color in the light.
