Abstract
A near-infrared hybrid lens system for imaging a wide field-of-view scene onto an image plane includes (a) a first cast lens positioned closest to the scene and at least partly transmissive to near-infrared light, (b) a second cast lens positioned closest to the image plane and at least partly transmissive to near-infrared light, and (c) a wafer-level lens at least partly transmissive to near-infrared light and disposed between the first cast lens and the second cast lens, wherein the wafer-level lens has (i) a planar substrate with a first surface facing away from the image plane and a second surface facing the image plane, (ii) a first lens element disposed on the first surface, and (iii) a second lens element disposed on the second surface.

A near-infrared hybrid lens system for imaging a wide field-of-view scene onto an image plane, comprising:
- a first cast lens positioned closest to the scene and at least partly transmissive to near-infrared light;
- a second cast lens positioned closest to the image plane and at least partly transmissive to near-infrared light;
- and
- a wafer-level lens at least partly transmissive to near-infrared light and disposed between the first cast lens and the second cast lens, the wafer-level lens including
- (a) a planar substrate having a first surface facing away from the image plane and a second surface facing the image plane,
- (b) a first lens element disposed on the first surface, and
- (c) a second lens element disposed on the second surface;
- wherein the first lens element and the second lens element are of a first material that is different from material of each of the first cast lens and the second cast lens.
