BYTECH Far UVC 222nm Light Excimer Lamp
1. Ultraviolet sterilization technology
Ultraviolet Wavelength Division
UVGI:
Ultraviolet germicidal lamp: ultraviolet radiation, a light source with a peak wavelength of 253.7nm
<200nm ultraviolet ray produces ozone, mercury has a characteristic spectrum at 185nm
Far UVC
Far UVC of 200nm~230nm is a new tool to control the spread of bacteria and viruses in the air effectively. According to research, 222nm ultraviolet radiation cannot easily penetrate the tear layer and the stratum corneum of the skin. The 222nm wavelength is proven to be safer and more effective than the existing 254nm ultraviolet.
UVA-2
Reach epidermis,but the shin and turn red
Proper irradiation can treat and prevent rickets long-term exposure to the skin and eyes can lead to skin cancer,cataracts and a weakened immune system
UVA-1
Reach dermis,cause skin to age and wrinkle
Mainly cause pigmentation
2. Principle of UV Sterilization-222nm Photobiological Safety

Far UVC 222nm Light Photobiological Safety
Penetration of UV wavelengths into human skin: Arrows represent an estimate of 90% absorption depth.UV-C wavelengths at 222nm do not appear to penetrate the stratum corneum; whereas, 254nm does penetrate into upper epidermis. UV-B wavelengths, such as 300nm, do penetrate to the critically important germinative(basal) layer of the epidermis and have sufficient energy to mutate DNA. UV-A wavelengths at 340nm, 360nm, and 400nm penetrate well into the dermis, but the lower photon energies are far less damaging than 300nm. |

Penetration of UV wavelengths into human eye. UV-C wavelengths at 222 nm hardly penetrate to the corneal epithelium; whereas, 254nm does penetrate well into the epithelium and into the stroma. There is some evidence of penetration even to the endothelium. UV-B wavelengths, such as 300nm do penetrate to the lens, and oblique rays to the critically important germinative layer of the ledsbahind the iris and have sufficient energy to mutate DNA. UV-A wavelengths are strongly absorbed by fluorophores in the lens and protect the retina. |
3. Principle of UV Sterilization
|
|
UV-C 222nm sterilization and disinfection also known as UV disinfection or ultraviolet germicidal irradiation (UVGI) works by breaking down certain chemical bonds and scrambling the structure of DNA, RNA and proteins, causing a microorganism to be unable to multiply. Under a certain dose, Far UV-C 222nm can kill most bacteria and viruses within 1 second.
The sterilization and disinfection rate of far UV-C 222nm is related to target microorganism and irradiation dose.

4. 222nm narrowband filter:
| When the excimer lamp is working, there are traces of 235nm, 258nm and 325nm spectrum lines. Adopt a filter to filter harmful wavelengths makes it safer to use. | |
