Erchonia's patent-pending line of 3LT® Lasers is headed up by the PL5000. Completely redesigned to reflect the features and functions requested by the doctors and practitioners that have been using Erchonia 3LT® Lasers to treat their patients since 1996. The PL5000 is a variable frequency, four diode laser that is encased in a custom designed, aircraft quality aluminum housing to resist the rigors of daily use in the real world. Ergonomically designed to fit hands of all sizes, the dual-diode heads, conveniently clip to the side of the laser when not in use, which increases security and prevents accidental ocular exposure to both patient and doctor. About the only mechanical piece on the PL5000 is the lock and key that enables the owner to prevent the unauthorized use of the laser. Configuration: Dual Probe, Four Diodes Diodes: (4) 5 milli Watt Wavelength: 635 nm Frequency: Variable from 1hz - 50,000hz Capable of up to ten (10) presets Programmable decimal point frequencies.
