What is 222nm Far UVC Technology?

Ultraviolet light is roughly divided into UVA, UVB or UVC according to its wavelength. All of these wavelengths are contained in the electromagnetic radiation emitted by the sun, but only UVA and UVB penetrate the ozone layer and reach the ground, where they are known to cause sunburn and skin cancer. Although UVC is absorbed within the ozone layer, its bactericidal effects are well known and have been used artificially to sterilize lamps. However, UVC can also be harmful, which limits its use.

The Columbia study found that far-UVC light(222nm UV light for sale filtered 222nm pure far UVC lamp) doesn't penetrate the tear layer of the eye or the outer layer of dead cells in the skin, so it doesn't damage living cells in the body. It is safe for human exposure. This is different from UVC light, which has been shown to be harmful to the skin and eyes. Columbia University is not the only institution to find that Far-UVC light is safe for human beings to use. A joint study between Kobe University in Japan and Ushio, Inc. found that "repeated irradiation of 222nm ultraviolet radiation (UV-C) with high disinfection power does not cause skin cancer, suggesting its safety on human skin and eyes."

Researchers at the University of Hiroshima also discovered that UV light 222nm can be effective against the current virus, the same as 254nm UVC. These researches showed that 222nm UVC has the same germicidal effect as 254nm and is safe for human exposure at the same time, it can be used in occupied space, the 222nm UVC is a whole new disinfection technology, it will bring about disruptive change in the germicidal field.

Why a UV Filter is Needed for Excimer Lamps?

The new research showed that the UVC wavelength < 230nm is safe for human skin, that above 230nm is harmful. The spectrum of Krcl excimer lamp is 222nm center wavelength and with a low value at 230-280nm, so the excimer lamp without a UV filter will be still harmful for your skin and eyes. A high quality UV bandpass filter is needed to remove the value at 230-280nm, it can make the lamps pure 222nm and completely safe.
