Because of its ability to cause chemical reactions and excite fluorescence in materials, ultraviolet radiation has a number of applications. The following table gives some uses of specific wavelength bands in the UV spectrum.
* 13.5 nm: Extreme ultraviolet lithography
* 30–200 nm: Photoionization, ultraviolet photoelectron spectroscopy, standard integrated circuit manufacture by photolithography
* 230–365 nm: UV-ID, label tracking, barcodes
* 230–400 nm: Optical sensors, various instrumentation
* 240–280 nm: Disinfection, decontamination of surfaces and water (DNA absorption has a peak at 260 nm), germicidal lamps
* 200–400 nm: Forensic analysis, drug detection
* 270–360 nm: Protein analysis, DNA sequencing, drug discovery
* 280–400 nm: Medical imaging of cells
* 300–320 nm: Light therapy in medicine
* 300–365 nm: Curing of polymers and printer inks
* 350–370 nm: Bug zappers (flies are most attracted to light at 365 nm)
