Ultra-Thin Lenses Halve Incident Wavelength to Make Infrared Light Visible

Ultra-thin lenses that make infrared light visible

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.

Ultra-thin lenses halve incident wavelength to make infrared light visible

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.

A metalens that can half the wavelength of incident light

Metalenses are flat, perform in the same way as normal lenses and do not need to be made of glass The ETH researchers succeeded in creating the first lithium niobate metalenses with precisely engineered nanostructures. While functioning as normal light focusing lenses, these devices can simultaneously change the wavelength of laser light. When infrared light […] The post A metalens that can half the wavelength of incident light appeared first on…
