Researchers from the MPIK in Heidelberg used an atomic gas as a time-dependent lens to shape and spectrally manipulate intense high-frequency laser pulses. This gas-based optical element could pave ...

Photography has everything to do with light. Therefore, the more we know how it behaves and interacts with our equipment, the greater the chance of getting a successful photo. This time, we are going ...

Physicists at ETH Zurich have developed a lens that can transform infrared light into visible light by halving the wavelength of incident light. The study is published in Advanced Materials. Lenses ...

Even after successful cataract surgery, many patients still need eyeglasses or contacts to achieve the best possible near and distance vision. But a newer option—the Light Adjustable Lens (LAL)—offers ...

Light-matter interaction describes the ways photons interact with atoms, molecules, electrons, excitons, phonons, plasmons, defects, and nanostructures. At the nanoscale, these interactions can be ...

Light Lens Lab has announced that its long-awaited 75mm F/2 SP-II for Leica M mount is now officially in production. The company says manufacturing will begin once it finishes fulfilling orders for ...

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 ...
