NS Nanotech boosts far-UVC LED output by 60%
US-based company NS Nanotech has increased the power output of its far-UVC ShortWaveLight 215 semiconductor emitter by more than 60 percent to deliver more effective human-safe disinfection of air and surfaces in occupied spaces.
Version 1.1 of the ShortWaveLight 215 Emitter generates 500 µW of radiant energy, enough power to constantly disinfect a cubic metre of air in an office cubicle, automobile interior, airplane cabin, or other confined space.
The NS Nanotech ShortWaveLight 215 Emitter, introduced in September 2024, is claimed tone the world’s only solid-state semiconductor to produce 215nm far-UVC light.
Far-UVC light at wavelengths from 200-230nm neutralises airborne pathogens that cause Covid, measles, TB, bird flu, and numerous other deadly diseases. And 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.
“The additional power output we have achieved with our ShortWaveLight 215 semiconductor chip opens up new pathways for far-UVC photonic disinfection applications,” said NS Nanotech CEO and co-founder Seth-Coe Sullivan. “Equally important, Version 1.1 demonstrates the potential for rapid additional ongoing improvements that will be possible with our groundbreaking far-UVC semiconductor technology. We've increased power output by increasing device efficiency, so this new level of effectiveness is achieved at the same input power levels as the Version 1.0 device.”
“The beauty of working with semiconductor technology is our ability to develop and deliver constant improvements in far-UVC disinfection performance, starting with power output and, eventually, additional form factors and longer product lifetimes,” Coe-Sullivan said.
NS Nanotech is shipping a ShortWaveLight 215 Module that integrates a compact power supply with the emitter in a modular product design for easy installation in confined occupied spaces where other ultraviolet light sources cannot be easily deployed. Running on a standard 12-volt power source, the power supply is connected to the emitter by a flexible set of wires providing disinfection application designers with optimal flexibility.
