New technology allows you to see in the dark with any glasses

Scientists from Europe and Australia have created a unique technology that allows you to see clearly in the dark. An ultra-thin film is applied to ordinary glasses.

Researchers from the Australian National University, together with scientists from Italy, Great Britain, Germany, France and Bulgaria, have created a revolutionary technology – a film based on nanometer-sized crystals. It can convert infrared light, which is invisible to the human eye, into a visible image.

Recall that infrared radiation is electromagnetic radiation that occupies the spectral region between the red end of visible light and microwave radio emission. The optical properties of substances in infrared radiation differ significantly from their properties invisible radiation.

The authors of the development claim that they managed to “make the invisible – visible.” The film, which consists of nanocrystals, is hundreds of times thinner than a human hair. It is applied to the lenses of ordinary glasses and acts as a filter that allows you to see in the dark.

The new technology for controlling light uses the properties of the metasurface of ultra-thin films, in which its optical properties vary at each individual point.

The authors of the development note that they were the first to be able to convert infrared light into a visible image on an ultrathin screen. In addition, the latest technology is very light, cheap and easy to mass-produce. This is what makes it a promising alternative to modern night vision devices, which are expensive and not always convenient.

An article describing the development was published in Advanced Photonics.
