in the BEAM SIZE window on the LCD display. It is also displayed on the handpiece
LED spot size indicator.
Note:
handpiece LED spot size indicator always displays actual handpiece state, i.e. it
will display previously used spot size until
Save
button is pressed and the zoom lens
moves to new position.
The treatment area (laser beam spot size on the skin) will be also illuminated by the red
aiming beam in
Ready
mode. The spot size of the aiming beam is changing
proportionally to the actual laser beam spot size.
The system will keep pre-selected
Fluence
value constant, no matter what spot size have
been chosen by the user. However, if the pre-set
Fluence
level can not be supported with
selected spot size, the system will automatically reduce the Fluence to the maximum
possible level and reflect the change on the LCD display The
Pulse Duration
will be
automatically adjusted to the higher value by the system software if selected Fluence is
too high and can not be achieved with currently selected
Duration.
Note:
Pulse
Duration
settings range is always limited by selected Fluence, i.e. some
pulse widths may not be available at certain combinations of Fluence and Beam Size
settings. This is normal.
LONG PULSE MODE
All pulses with Durations above 10 ms (Nd:YAG) and 7 ms (Alexandrite) are
“stretched”, i.e. consist of a train of shorter pulses spaced in time. The sum of the pulse
widths in each train is equal to 10 or 7 ms respectively. This mode of operation is called
Long Pulse Mode and is designed to provide a certain degree of pain relief for patients
with too sensitive skin. It is not recommended to use this mode for treatment of areas
with very fine (thin) hair.
Example:
To change the
Fluence
in Parameter Settings #2, do the following:
1.
Press Memory Button #2
2.
Press
Fluence
button to select Fluence option (will be displayed in highlighted
mode)
3.
Use
+
button, if you want to increase the fluence and
–
button, if the fluence must
be decreased or directly enter desired fluence with a keypad.
4.
When desired fluence value is displayed, press
Save
button to switch the laser to
Ready
mode.
