Simplified representation of early PureFize Far-UVC prototype emission, showing deep-UV output below 240 nm. The chart is intended to illustrate the demonstrated wavelength region, not final product performance. Prototype data. Further development, system optimization, performance validation, and safety validation are ongoing.
