The Pulse Duration Knob
The Pulse Duration Knob sets the duration (exposure time) of the laser emission and
it functions as described below:
Turning the knob clockwise increases the exposure time up to 2000 ms.
Turning the knob past the 2000 ms setting or pushing the knob places the system
in Continuous Wave (CW) mode. In CW mode, the Interval Time knob is
disabled.
Turning the Pulse Duration knob counter-clockwise from CW mode returns the
system to the previous mode: Single Shot or Repeat.
Turning the knob counter-clockwise decreases the exposure time. The lowest
available exposure time is 10 ms.
The Pulse Duration Knob adjusts the exposure time to the following values in
milliseconds:10, 20, 50, 100, 150, 200, 250, 300, 400, 500, 700, 1000, 1500, 2000
ms and Continuous Wave (CW).
NOTE: In CW (Continuous Wave) mode, depending on the thermal load of
the system, the system may shut down prior to the footswitch being
released, with an indication in the LCD display. It is not recommended
to use exposure times longer than 2 seconds in CW mode.
The Power Knob
The Power Knob is used to adjust the treatment laser power and it functions as
described below:
Turning the Power Knob clockwise increases the laser power.
Turning the Power Knob counter-clockwise decreases the power power.
The Power Knob adjusts the power setting to the values shown in Table 2-1.
Table 2-1 532 Green Laser Power Values (in milliwatts)
30 40 50 60 70 80 90 100 110 120 130 140
150 160 170 180 190 200 220 240 250 260 280 300
320 340 350 360 380 400 420 440 450 460 480 500
550 600 650 700 750 800 850 900 950 1000 1100 1200
1300 1400 1500 1600 1700 1800 1900 2000
NOTE: The
PurePoint™
laser determines the 532 green laser maximum
available power and limits the user setting to that maximum value if less than
2 W. The maximum selectable power may be less than 2 W (2000 mW) because
of the degradation of the laser engine over time.
