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.

The wavelength is what determines light’s color, and these LEDs are amber (605-nanometer wavelength), light red (630 nm), deep red (680 nm), and near infrared (855 nm).

Star-favored, board-certified aesthetics physician Dr. Glenicia Nosworthy explains how to choose the right high-tech tool for ...

Near-infrared light sits just outside the range of wavelengths that humans can normally detect. Some animals can sense infrared light, although probably not well enough to form images.

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.

Red light therapy (RLT), also known as low-level laser therapy (LLLT) or photobiomodulation (PBM), is a non-invasive treatment that utilizes specific wavelengths of red and near-infrared light ...

For example, when an infrared laser with an 800-nanometer wavelength hits the metalens, visible light at 400 nanometers emerges, focused to a sharp point.

Finally, the tellurium meshes, especially the infrared vision capability they offered, were tested on healthy macaques, an ...
