Researchers at the University have created a system of UV disinfection using visible light lasers. The COVID-19 pandemic has vastly increased the need and urgency for effective and safe sanitation of large spaces including hospitals, public transportation, and meeting spaces. This fiber optic system tracks existing internal wiring and emits light via diodes that distribute ultraviolet light throughout a space to maximize disinfection. The UV light is emitted at a wavelength of less than 222 nm, making it safe for human contact. There are no lamps or filters required.
