Far-UVC ultraviolet light, at wavelengths from 200-to-230 nanometers, deactivates viruses in the air and on surfaces but doesn't penetrate the skin far enough to reach live cells.

How Far-UVC light could be key in curbing the next airborne pandemic 03:31. Five years ago, the COVID-19 pandemic first swept across the U.S., infecting millions and claiming hundreds of thousands ...

NS Nanotech's ShortWaveLight™ 215 Emitter, the world’s highest-energy semiconductor ultraviolet light source, enables human-safe air and surface disinfection in occupied spaces with far-UVC light.

Ultraviolet light is invisible to the eye, ... and with small sample sizes. We will need trials with rigorous ethical approvals to investigate the full far UVC impact on humans.

In contrast, dual-comb spectroscopy exposes the sample to broadband light from a frequency comb itself. As the input is broadband, the output is also broadband. However, the light passing through the ...

An ultraviolet photon-counting dual-comb spectrometer. Two ultraviolet frequency combs of slightly different pulse repetition frequencies are generated at very low light levels by nonlinear ...

Ultraviolet (UV) microscopy is a type of light microscopy that utilizes UV light to generate a magnified image of the sample being analyzed. As a result of the shorter wavelength of UV light than ...

Ultraviolet light is well-known for its ability to kill germs, including ones that cause food to spoil. And while there doesn't tend to be any food-preserving UV light in our refrigerators, a new ...

Ultraviolet (UV) sanitizers use UV rays to sterilize surfaces. UV sanitizers have been shown to work, with some devices eliminating nearly 99.99% of bacteria, fungi, and viruses that cause disease.
