Record-breaking metalens could revolutionize optical technologies

Traditional lenses—like the ones found in eyeglasses—are bulky, heavy and only focus light across a limited number of wavelengths. A new, ultrathin metalens developed by researchers at the University of California, Berkeley, ...

Researchers create focus-free camera with new flat lens

Using a single lens that is about one-thousandth of an inch thick, researchers have created a camera that does not require focusing. The technology offers considerable benefits over traditional cameras such as the ones in ...

High-tech contact lenses correct color blindness

Researchers have incorporated ultra-thin optical devices known as metasurfaces into off-the-shelf contact lenses to correct deuteranomaly, a form of red-green color blindness. The new customizable contact lens could offer ...

Revolutionary ultra-thin 'meta-lens' enables full-color imaging

Light of different colors travels at different speeds in different materials and structures. This is why we see white light split into its constituent colors after refracting through a prism, a phenomenon called dispersion. ...

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 ...
