Proof-of-concept Study on Disinfection and Healing Acceleration Capabilities of 222nm Wave Length Narrow Band Ultraviolet Lighting Device

SafeZoneUVC® uses a Krypton Chloride (Kr-Cl) excimer lamp as its light source. The Kr-Cl excimer lamp emits UVC light having a main wavelength of 222 nm when the Kr-Cl exciplex is deactivated to non-excited state molecule in the lamp. This 222 nm UVC light can inactivate bacteria, while the Kr-Cl excimer lamp also emits UVC light having a wavelength of 230 nm or more. SafeZoneUVC® effectively eliminates UVC light with a wavelength of 230 nm or more by incorporating an appropriate optical filter inside the unit and also utilizing an opaque guide to ensure that light is not dispersed beyond the target area.
