A science experiment shows how a special lens bends light in a way that hides objects from view, explaining the physics ...

Physicists have developed a lens with 'magic' properties. Ultra-thin, it can transform infrared light into visible light by halving the wavelength of incident light. Lenses are the most widely used ...

Cameras may soon see without lenses, and the change could be as profound as the leap from film to digital. A new imaging ...

For centuries, lenses have worked the same way: curved glass or plastic bending light to bring images into focus. But traditional lenses have a major drawback—the more powerful they need to be, the ...

WASHINGTON--(BUSINESS WIRE)--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 ...
