 LEOTM: Optimised Light Energy

• Optimises the duration of the pulse, parameters
  of the pulses shape and fluence with the most
  efficient optic energy for numerous applications
  using two types of technology:

   - Advanced Fluorescence Technology (AFTTM)
    - Equally Distributed Fluence (EDFTM)
EDFTM: Equal Distribution Fluence


                 Full uniform fluence
                 Duration of the long
                pulse composted of
                multiple mini-pulses
                 Moderate energy peak

AFTTM: Advanced Fluorescence Technology

                 "The AFT filtered light passes
                  through a 2nd fluorescent filter
                  which converts the
                  “ineffective” UV light, into an
                  optimum spectrum.
                 The improvement in the long
                  wave peaks is related to their
                  application:

                    In the Blue is for Acne
                    In the Green is for SR
                    In the Red is for HR

LEO   TM   : Absorption window for different chromoforums
          LEO     TM   vs. IPL
 Two essential differences between the
  LEO and the IPL:


  1. Technology

  2. Pulse form and duration
             LEO TM vs. IPL
      Pulse duration and pulse form
• In a common IPL the pulse form is composed of
  various pulses (normally between 1-3) each one
  with a duration of between 2-4 msec and with a
  delay between pulses (normally between 5-
  50msec.
• The energy peak of each pulse is high (peaked
  form) and each pulse in the sequence has less
  energy (due to the drop in tension in the bench of
  condensers).
• The Lovely II makes the output of a smaller energy
  peak but with equally distributed fluence (flat form)
  with a duration of up to 50 msec.
