If you could chop up a meter-long stick into a billion little pieces, each would be a nanometer (nm) long. Materials made of particles with diameters in the nanoscale range are being used in targeted ...

Under the JST Strategic Basic Research Program PRESTO, Associate Professor Ayumi Ishii of Teikyo University of Science with her team members has developed a new near-infrared light sensor by using a ...

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 ...

Scientists have developed a lens-free mid-infrared camera using a modern twist on pinhole imaging. The system uses nonlinear crystals to convert infrared light into visible, allowing standard sensors ...

Neuroscientists and materials scientists have created contact lenses that enable infrared vision in both humans and mice by converting infrared light into visible light. Unlike infrared night vision ...

Researchers at the Indian Institute of Science (IISc) have fabricated a device to increase or “up-convert” the frequency of short infrared light to the visible range. Up-conversion of light has ...

Humans have a new way of seeing infrared light, without the need for clunky night-vision goggles. Researchers have made the first contact lenses to convey infrared vision — and the devices work even ...

Red light therapy (RLT) involves exposing the body to low-wavelength red or near-infrared light (IRL). Red and near-IRL differ slightly in terms of wavelength and visibility. Red light is visible to ...
