A completely flat, ultrathin lens can focus different wavelengths of light at the same point, achieving instant color correction in one extremely thin, miniaturized device. Most lenses are, by ...

Caltech engineers have developed a new camera design that replaces the lenses with an ultra-thin optical phased array (OPA). The OPA does computationally what lenses do using large pieces of glass: it ...

Astronomers have discovered more than 5,000 planets outside of the solar system to date. The grand question is whether any of these planets are home to life. To find the answer, astronomers will ...

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 ...

Paper-thin optical lenses simple enough to mass produce like microchips could enable a new generation of compact optical devices. Researchers have fabricated and tested flat lenses called Fresnel zone ...
