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 ...

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 ...

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 ...

A study participant puts in a contact lens. Researchers developed lenses with nanoparticles that convert infrared wavelengths into visible light that humans can perceive. Yuqian Ma, Yunuo Chen, Hang ...

Infrared light passes through the metal lens and is converted into violet light and focussed in a focal point due to the material and the special surface structures – enlarged in the magnifying glass.
