  • Shaped gradient fabrication in lenses by molding from axial gradient
    Patent number: 5236486
    Abstract: Shaped gradient profiles of index of refraction in lenses are fabricated from axial gradients. While the resulting lens has both radial (or cylindrical) and axial components, and, strictly speaking, is not a pure radial (cylindrical) gradient, nonetheless, the presence of both the radial and axial components or cylindrical and axial components provides lens designers with greater flexibility in lens design than heretofore existed.
