A new type of flat, ultrathin lens designed to be free of chromatic aberrations has been developed by researchers in the US. The device has a variety of potential applications, from ultralight imaging ...

image: In the future, camera lenses could be thousands of times thinner and significantly less resource-intensive to manufacture. Researchers from Chalmers University of Technology, Sweden, now ...

Ultra-thin flat lenses suitable for photography are one step closer after a team of researchers at Harvard University made a major leap forward with its prototype wafer-thin flat lens. The new lens ...

Thin, simple diffractive lenses are notorious for their blurry images, so they have never been used in astronomical observatories. But if you could improve their clarity, using diffractive lenses ...

To take high-quality images of the stars, astronomers usually need thick, curved lenses to bend the light precisely. But researchers have designed a flat lens that can take sharp images of the night ...

Researchers developed a new ultra-thin planar (flat) "metalens" that can potentially replace the stacked, bulky lenses used in telescopes, microscopes, smartphones, cameras and other gadgets. Despite ...

Researchers in Israel have made a new type of contact lens that can correct a form of red–green colour blindness known as deuteranomaly. By incorporating plasmonic metasurfaces into standard contact ...
