20220196981 | Lens Systems Using Free Form Elements to Match Object Space and Image Space, and Methods Therefor - Lens system suited for a wide variety of applications uses a variety of freeform lens shapes or surfaces, defined typically by Zernike, Chebyshev or X-Y polynomials to enable low f-number, wide field of view, improved off-axis performance, and other optical characteristics not achievable with rotationally symmetric lenses. The design can be implemented using existing manufacturing techniques. | 2022-06-23 |
