MEMS chips get metatlenses

Lens technologies have advanced across all scales, from digital cameras and high bandwidth in fiber optics to the LIGO lab instruments. Now, a new lens technology that could be produced using standard computer-chip technology ...

Metasurfaces enable improved optical lens performance

Producing the perfect color images we need and love often requires multiple, heavy lenses so that each color focuses in exactly the same plane. Now Penn State engineers have developed a new theory that solves the problem ...

Brittle starfish shows how to make tough ceramics

An international team lead by researchers at Technion-Israel Institute of Technology, together with colleagues from the European Synchrotron, Grenoble, France, have discovered how an echinoderm called Ophiocoma wendtii, known ...

Novel lenses enable X-ray microscopy with record resolution

Scientists at DESY have developed novel lenses that enable X-ray microscopy with record resolution in the nanometre regime. Using new materials, the research team led by DESY scientist Sasa Bajt from the Center for Free-Electron ...

A microlensing event seen from three positions in space

The path of a light beam will be bent by the presence of mass, an effect explained by General Relativity, and a massive body can therefore act like a lens - a so called "gravitational lens" – to distort the image of an ...

New type of electron lens for next-generation colliders

Sending bunches of protons speeding around a circular particle collider to meet at one specific point is no easy feat. Many different collider components work keep proton beams on course—and to keep them from becoming unruly.
