Mar 16, 2020 · UV Light Kills Coronavirus For several decades, it has been known by scientists that broad-spectrum germicidal UV light, with wavelengths between 200 and 400 nanometers (nm), is very effective at killing bacteria and viruses by destroying bonds that hold their DNA together. This standard UV light is often used to decontaminate surgical equipment. Sep 23, 2020 · In order for UV light disinfection to be effective, however, several critical factors must be controlled. First, the rays need to be at the correct wavelengths for the target virus. While this usually depends on the specific organism, anywhere between 200-300 nm is "considered germicidal" with peak effectiveness at 260 nm, says Malley. Only near UV is of interest for UV photography, for several reasons. Ordinary air is opaque to wavelengths below about 200 nm, and lens glass is opaque If you want to measure UV from one of these lamps then looking at the 405 nm light isn't any more helpful than looking at the yellow doublet.light into bands of wavelengths and focuses them onto the plane of the photodiode array.
