UVB Wavelengths UVB has a mid-range wavelength measuring 280 nm to 320 nm and works with many of the photo initiators in use today. Like UVA, it is used for curing coatings, adhesives and inks but is also highly utilized for UV applications involving: Disinfection; Sterilization ; UVC Wavelengths The shortest and weakest wavelength is UVC, which measures 200 to 280 nm. The UV region covers the wavelength range 100-400 nm and is divided into three bands: UVA (315-400 nm) UVB (280-315 nm) UVC (100-280 nm). 2019-09-09 · The terms ultraviolet light and UV refer to a relatively large wavelength range between 400 nanometers (nm) and 100 nm. It falls between violet visible light and x-rays on the electromagnetic spectrum. UV is described as UVA, UVB, UVC, near ultraviolet, middle ultraviolet, and far ultraviolet, depending on its wavelength.
