Lenses are crucial to light-enabled technologies. Conventional lenses have been perfected to achieve near-diffraction-limited resolution and minimal chromatic aberrations. However, such lenses are ...

Addressing a controversy first raised around 1910, two physicists have performed experiments with the aid of an engineer that validate anew the special theory of relativity’s limitations on the speed ...

The invisible light spectrum, encompassing ultraviolet and infrared wavelengths, has long beguiled the human eye. A revolutionary lens technology is now making this unseen light accessible, heralding ...

The famous double-slit experiment, which demonstrated that light is both a wave and a particle, has been performed using “slits in time”. The techniques involved present a new way to manipulate light ...

Applied physicists in the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have demonstrated a new way to structure light in custom, repeatable, three-dimensional patterns, ...

A versatile, professional-grade lens with superior light-gathering capability, though there's a compromise to be made in terms of weight. Chromatic aberration and coma are significantly corrected. Why ...

In this International Year of Light (IYL 2015) we don’t just want to tell you about how great light and its applications are, we want to show you too. So in this short video, industrial scientist and ...

Scientists have created contact lenses that they claim allow people to see in the dark with the help of infrared light, an invention that could allow colorblind people to see colors again, or spies to ...
