Hybrid MOD-Enmat Lens
Researchers at the University of Arizona have designed an optical device comprising a multiple-order diffractive Fresnel lens (MOD-DFL) and an achromatizing compensation mechanism that reduces refractive dispersion created by the MOD-DFL, thereby reducing the focal range of the MOD-DFL. A method is also provided of using the optical device in an image...

Fabrication of Diffractive Patterns on Aspheric Mirror Substrates
This technology is a novel way of printing diffractive pupils through a means of maskless lithography on any surface.
Background:
Currently, the fabrication of diffractive pupils is limited to planar surfaces because there are many issues and restrictions with printing diffractive pupils on aspheric mirror surfaces. Printing diffractive structures...
