Abstract
Aspheric lens structures with dual aspheric surfaces and fabrication methods thereof are disclosed. An aspheric lens structure includes a first lens component with an aspheric top surface disposed on a second lens component, wherein the interface between the first lens component and the second lens component is spherical. The second lens component includes an aspheric back surface, wherein the radius of curvature of the aspheric top surface of the first lens component is different than the radius of curvature of the aspheric back surface of the second lens component. The second lens component may also include a planar back surface with a third lens component disposed on the planar back surface of the second component. The third lens component includes an aspheric back surface, wherein the radius of curvature of the aspheric top surface of the first lens component is different than the radius of curvature of the aspheric back surface of the third lens component.
