Lenses are used to bend and focus light. Normal lenses rely on their curved shape to achieve this effect, but physicists from the University of Amsterdam and Stanford University have made a flat lens ...

Small, lightweight, and with no shortage of lumens, BYB Tech’s Focus bicycle light was designed to make you be seen on the road just as if you were a car. The more lumens your light can put out, the ...

Building upon years of research by Stanford University, and with a PhD thesis and five further years of research in hand, Ren Ng has finally launched the infinite-focus, light field photography ...

If wearing a virtual reality or augmented reality headset is ever to become commonplace, hardware manufacturers will need to figure out how to make the devices small and lightweight while ensuring ...

Metalenses -- flat surfaces that use nanostructures to focus light -- promise to revolutionize optics by replacing the bulky, curved lenses currently used in optical devices with a simple, flat ...

Scientists have used a new lens to focus all the colors of the rainbow into one point. This is the first time a single lens has been used to focus the entire spectrum of light, including white light.
