The shorter the wavelength, the more UV radiation is absorbed by the Earth’s atmosphere. This is why organisms on our planet have no natural defences against this type of light. The most efficient wavelengths for disinfection are between 250 nm and 280 nm. LEDs emitting in this spectrum are therefore called germicidal LEDs.
Our portfolio of germicidal LEDs includes wavelengths of 255 nm, 265 nm, 272 nm and 275 nm. Their optical power per chip ranges up to 100 mW.
