Researchers have been able to create a new camera that doesn't require focusing using a single lens that is very thin. The technology has significant benefits over traditional cameras, like those used ...

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 ...

A flat lens that allows a camera's focus to be maintained for objects separated by distances of up to six meters could offer benefits to smartphones and mobile devices, including the potential removal ...

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 ...

High-numerical-aperture optical lenses offer very high resolution and are particularly useful for low-light-intensity applications, such as single-photon optics. The numerical aperture is a measure of ...
