3. Connect the heptafurcated fiber from the rear of the Sample Chamber to the seven spectrometer
channel SMA connectors on the front of the spectrometer rack. The computer's operating system
will recognize the new hardware and load the appropriate drivers for each of the seven
spectrometers in the LIBS system.
4. Start the OOILIBS software and configure your spectrometers (see
5. Attach the laser cables from the laser to the laser power supply. See your laser’s documentation
for specific instructions.
6. Using the supplied BNC cables, attach them to the connectors on the back of the laser power
supply, then connect them to the Laser Trigger OUT, Lamp Sync IN, and Q-Switch OUT to the
BNC connectors on the rear panel of the spectrometer rack.
Caution
Beware of lasers that use negative logic and/or high voltage outputs. Lamp Sync
signals as high as 33 volts have been observed in testing, and the electronics in the
LIBS2000+ may not survive pulse voltages of this intensity. The spectrometer
electronics are designed to drive the 50ohm loads associated with BNC connectors,
and all signals are 5V TTL.
Laser Connection Spectrometer
Connection
Function
External Trigger
(IN)
Laser Trigger OUT
This cable is connected to the external trigger
connection of the laser. It initiates a laser fire.
Flash Lamp Fire
(OUT)
Lamp Sync IN
This cable is connected to the lasers’ strobe
synchronization output. It tells the spectrometer
the exact time the strobe is firing. If such a line
is not available, connect this to the Laser
Trigger OUT
cable using a BNC tee.
External Q-switch
(IN)
Q-Switch OUT
This cable connects to the external Q-switch of
the laser. It fires the Q-switch under software
control. Most lasers have a switch that must be
set to allow this to happen. If only an external
trigger input is available, you do not need to use
this line, but you will have no control over the Q-
switch event.
7. If you are using the LIBS Imaging Module, plug in its 12 VDC power supply and connect the
firewire cable from the camera to the PC. Then install the PixeLink software from the LIBS and
PixeLink Software CD that comes with the imaging module. See the LIBS Imaging Module
Installation and Operation Instructions that came with your LIBS Imaging Module. Refer to
