Sub-Cellular Imaging and Manipulation via Hyper-Numerical Aperture Imaging Surfaces
High spatial resolution and detection of sub-cellular physiology (like respiration) is achieved using a near-field imaging surface that can be manipulated mechanically inside living biological matter. This new near-field probe is photon efficient, unlike most near-field scanning probes, and is a true imaging probe, not a point source or point collector....

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...
