Abstract
An optical lens comprising a lens body that transmits light in an optical path there through, wherein the lens body consists of an anterior surface, a posterior surface, and a medium there between, further wherein one of the anterior surface and the posterior surface has a single curvature and the other of the anterior surface and the posterior surface has at least two optical zones each having a different curvature. An optical system, comprising a multi-photon endoscope having a distal end, and the optical lens disposed in the distal end. A method for obtaining an image of an object comprising providing the multi-photon endoscope, propagating light from the endoscope scanner one optical zone of the lens to focus the light at a focus location, and propagating light from the scanner through a different optical zones of the lens to focus the light at a different focus location.
