The product group Leonardo® Duster are laser systems with functions and ergonomics specially developed for medical applications. User-friendly menu navigation and microprocessor-supported control ensure reliable operation while allowing physicians to concentrate on the essential aspects of treatment. A touchscreen is used to set treatment parameters, such as Power (W) in Continuous mode, Pulse energy (J) and Frequency (Hz) with Pulse width options in Pulse mode. The Thulium doped fiber laser module produces coherent laser radiation with the wavelength of 1940nm±3nm (aiming beam 532nm +/-10nm). A beam transporting system delivers this energy to affected surfaces and organs.
