Three-surface wide field-of-view lens system
Abstract:
A three-surface wafer-level lens system for imaging a wide field-of-view scene onto an image plane includes (a) a first wafer-level lens with (i) a first substrate having a first planar surface facing the image plane, and (ii) a first lens element bonded to the first planar surface and having a first lens surface facing the image plane, and (b) a second wafer-level lens with (i) a second substrate having a second planar surface facing away from the image plane, (ii) a third substrate bonded to the second substrate and having a third planar surface facing the image plane, (iii) a second lens element bonded to the second planar surface and having a second lens surface facing away from the image plane, and (iv) a third lens element bonded to the third planar surface and having a third lens surface facing the image plane.
