Metalens Design Enables Reconfigurable Imaging
EVANSTON, Ill., March 29, 2019 — A Northwestern University research team has developed an imaging platform based on fully reconfigurable metalenses. The lenses focus light by exciting surface lattice resonances that are tuned by patterned polymer blocks on single-particle sites....
Lens-on-MEMS Technology Could Lead to More Compact Optical Devices
LEMONT, Ill., March 7, 2018 — In a collaboration between Argonne National Laboratory and Harvard University, researchers built a metasurface-based lens on top of a MEMS platform, creating a “lens-on-MEMS” device that focuses light in the mid-IR spectrum. The...
Flat Surface Lens Overcomes Limitations of Conventional Optics
Jun 22, 2017 — The telescope has been used for more than 400 years. Although there have been many designs created for looking at distant objects, there is a fundamental weakness with the lens system. By necessity, telescopes use curved lenses — which are...

Flat Lens Shows Promise For Lab-On-A-Chip Devices
AMSTERDAM, July 7, 2016 — A flat optical lens could help reduce the size of computer hard drives and enable further miniaturization of microscopes and other technologies. The lens, comprising thin layers of silver and titanium dioxide, offers a larger field of view and a...
Capasso Lab Reports Planar Metalens Designed
CAMBRIDGE, Mass., June 2, 2016 — Materials science has made a great leap forward towards replacing glass lenses with metasurface materials that are practical to manufacture and produce aberration-free, subwavelength-resolution images. The planar metalens could replace traditional...
Spray-on flat lens works in the UV
GAITHERSBURG, Md. – A new, easily fabricated metamaterial-based flat lens that bends and focuses UV light could improve photolithography, nanoscale manipulation and manufacturing, and even high-resolution 3-D imaging, say its developers, scientists working at the...
Spray-On Flat Lens Works in the UV
GAITHERSBURG, Md., May 24, 2013 — A metamaterial-based flat lens that’s easy to fabricate and that can bend and focus UV light could improve photolithography, nanoscale manipulation and manufacturing, and even high-resolution 3-D imaging, say scientists at the National...
New Candidates Sought for Metamaterial Conductors
AMES, Iowa, April 26, 2012 — A new method that evaluates different conductors for use in metamaterial structures could bring closer to reality super-efficient solar energy devices and superlenses that allow us to use visible light to see molecules like DNA.
