SEAS researchers have developed a so-called metacorrector, a single-layer surface of nanostructures that can correct chromatic aberrations across the visible spectrum and can be incorporated into ...

A single-layer of nano-structures on the surface of optical elements can correct chromatic aberrations across the visible spectrum, from simple lenses to “the super-complex objectives with as many as ...

These are images of a US Air Force resolution target, a microscopic optical resolution test, imaged with (left) and without (right) the metacorrector. The linewidth of the first line in group 7 of the ...

(Nanowerk News) Today's optical systems -- from smartphone cameras to cutting-edge microscopes -- use technology that hasn't changed much since the mid-1700s. Compound lenses, invented around 1730, ...
