Thanks to a high-powered new metalens currently under develpment at Harvard, we may be just short steps away from vision improvement running on a whole new level of nanotechnology.

New metalens technology from Harvard engineers could bring an end to many common vision problems.

The future just got radically brighter for all those of us who weren’t born with perfect vision. Thanks to breakthr…

‘Metalens’ breakthrough may revolutionize camera lenses as we know them

“Until recently, metalenses—flat ‘lenses’ that can focus light using nanopillars on their surface — were a cool-but-limited area of study when it came to photography,” DL Cade reports for Digital Photography Review. “Sure, these flat lenses are 100,000x thinner than glass, but they could only work with a limited range of colors, making it unlikely they’d appear in a cameras module any time soon.”

Bridging the Terahertz Gap

Optical frequency combs are widely-used, high-precision tools for measuring and detecting different frequencies — a.k.a. colors — of light. Unlike conventional lasers, which emit a single frequency, these lasersemit multiple frequencies simultaneously. The equally spaced frequencies resemble the teeth of a comb. Optical frequency combs are used for everything from measuring the fingerprints of…

A better hologram for fraud protection and wearable optics

Holograms are a ubiquitous part of our lives. They are in our wallets — protecting credit cards, cash and driver’s licenses from fraud — in grocery store scanners and biomedical devices. Even though holographic technology has been around for decades, researchers still struggle to make compact holograms more efficient, complex and secure. Researchers at the Harvard John A. Paulson School of…

Low-cost coloring technology developed by Harvard University’s PhD student

MEXICO: Mikhail Kats the PhD student from Harvard University’s Laboratory for Integrated Science and Engineering has recently created a new lightweight, low-cost coloring technology for both rough and smooth surfaces. An ultra-thin conductive metal coating that can be used with any material to make flexible smart clothes or efficient solar cells or light weight industrial paint, said researchers.

L’altra radiazione: l’infrarossa come fonte di energia rinnovabile?

Alle energie rinnovabili come sole, acqua e vento, potrà aggiungersi in futuro anche un’altra modalità di ottenere energia rinnovabile come quella ricavabile dal calore atmosferico , o per meglio dire, dalla radiazione termica emessa in continuo dalla superficie terrestre. Proprio su questo fronte sta lavorando un gruppo di ricercatori dell’Università di Harvard, tra cui l’italiano Federico…
