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 ...

This experiment revisits a long-running attempt to build a working camera lens and image system from scratch, then upgrades it into a usable camera for a live public event. After previously producing ...

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, ...

Laboratory of Behavioral Ecology and Evolution at Seoul National University Light and foraging ants seem totally unrelated, but they have one thing in common: they travel along time-reducing paths.

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 ...

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 ...

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 ...

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 ...
