UVC LED Disinfection

UV-C based LEDs are a relatively new technology. Examples of wavelengths currently commercially available include 255nm, 265nm, 275nm, and 285nm. However, UV-C LED technology is rapidly developing, and over time new wavelengths will be developed, costs will reduce and efficiencies will increase as has already happened within the red, infrared, blue, and UV-A wavelength LED ranges.

A wavelength of 265nm is considered the optimum as it’s the peak of the DNA absorption curve. However, disinfection and sterilization occur over a range of wavelengths. UV-C LEDs can be manufactured to target very specific and narrow wavelengths. This allows solutions to be tailored to the particular application need.
