200nm 220nm 222nm UV Narrow Bandpass Filter For Far UVC Light

The 200nm 220nm 222nm UV Narrow Bandpass Filter is a specialized optical filter that selectively allows light with a narrow wavelength range of 222nm to pass through while blocking all other wavelengths. This filter is designed to be used with lamps that emit Far-UVC light at a wavelength of 222nm, effectively killing bacteria and viruses without harming human skin or eyes.

 

Our filter adopts advanced hard coating technology, with good performance in transmission and cutting. It is typically made from high-quality optical materials such as fused silica, sapphire, or calcium fluoride, capable of transmitting UV light with high efficiency. Tell us your requirements and we can offer a range of customization options to tailor our products to your exact needs.

How is far UVC light used for disinfection and sterilization?

In the 32nd Tokyo Olympic Games, the Chinese Olympic delegation achieved "zero infection," while the "light vaccine" played a significant role during the epidemic. The "light vaccine" is a device that uses 222nm ultraviolet disinfection and sterilization technology, which can kill the new COVID-19 by destroying the genetic material and continuously and efficiently inactivating most pathogens, including viruses, bacteria, mold, and spores in a human environment.

 

Generally, excessive ultraviolet radiation may lead to human health problems, but ultraviolet light with a wavelength of 222nm cannot penetrate the stratum corneum of human skin, and it is harmless to the human body. Our far UVC lights with a 222nm filter to remove the harmful wavelength and radiate the pure 222nm. It has the same bactericidal effect as traditional ultraviolet lamps with a high sterilization rate against the new COVID-19; only a low dose of 1.2~1.7 mJ/cm², the 222nm ultraviolet lamps can sanitize 99.9% of the new COVID-19, and significantly reduce the concentration of virus in the environment.
