NS Nanotech Inc of Ann Arbor, MI, USA — a University of Michigan Electrical and Computer Engineering (ECE) spin-off co-founded by professor Zetian Mi in 2017 that develops gallium nitride nanowire LEDs for visible displays and UVC disinfection applications — has increased the power output of its far-UVC ShortWaveLight 215 semiconductor emitter by more than 60% to deliver more effective human-safe disinfection of air and surfaces in occupied spaces. Version 1.1 of the ShortWaveLight 215 Emitter generates 500μW of radiant energy, enough power to constantly disinfect a cubic meter of air in an office cubicle, automobile interior, airplane cabin, or other confined space.
Introduced in September 2024, the ShortWaveLight 215 Emitter is claimed to be the world’s only solid-state semiconductor to produce 215nm far-UVC light. Far-UVC light at wavelengths of 200–230nm neutralizes airborne pathogens that cause COVID, measles, TB, bird flu and numerous other deadly diseases. Also, because the short far-UVC wavelength doesn’t easily penetrate skin or eyes, it can be safer to use in occupied areas than traditional forms of UVC light used for disinfection at 254nm and other longer wavelengths.
