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.

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.

Researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) and Technical University of ...

Using their method, the ETH team achieved second-harmonic focusing over a wide spectral range—from near-ultraviolet to near-infrared wavelengths (760–1550 nanometers).

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.

How does the camera on the James Webb Space Telescope work and see so far out? – Kieran G., age 12, Minnesota Imagine a camera so powerful it can see light from galaxies that formed more than 13 ...
