Gradient-index wide-angle photographic objective design
Abstract
Wide-angle photographic lens systems utilizing axial gradient elements are studied. The resulting two- and three-element designs are compared with a six-element homogeneous wide-angle designed by Nippon Kigaku K.K., U.S. Patent 4,099,850. Practical considerations for manufacturing are also discussed.
