I. Included Components
The 785nm Integrated Raman Probe comes complete with an internal 350 mW spectrum stabilized laser
module that contains an integral Thermo-Electric Cooler (TEC) and thermistor for monitoring the internal
temperature of the laser platform. The unit comes complete with a laser enable switch for safety, an LED
readout, an output power control dial, a safety key lockout, a remote interlock, and an emergency shut-off
switch, Raman filter packs, beam shaping optics and high efficiency Raman spectra collection optics and a
custom fiber optic cable with a FC/PC termination. Additionally the 785nm Integrated Raman Probe comes
complete with a UL/CE, and IEC compliant control box providing a variety of power control options including
TTL, analog, and USB.
II. Laser Start-Up (controlling output power via front panel)
The following steps and illustrations should be followed when starting the 785nm Integrated Raman Probe.
Caution—use of controls or adjustments, or performance of procedures other than those specified herein
may result in hazardous radiation exposure.
1. Connect the DC power supply provided with the unit to the back of the control box.
Insert DC power
plug into socket.

2. Plug in the DC power supply into a standard 100 V –240 V AC electrical outlet making sure that the
Master Power key is set to the off (Vertical) position.
3. Connect the DB9 I/O cable of the probe into the front panel on the control box and secure with the
thumbscrews.

4. Insert the fiber optic cable from the probe into the FC/PC port of your spectrometer. Do not fully
tighten the connector because you will need to rotate the fiber later.
5. If measuring solid samples attach the distance regulator to the tip of the probe shaft. This will
reduce the working distance to ~0.5mm, allowing contact measurements.

6. Open the laser shutter.
7. Place solid sample in contact with the distance regulator, or if using a liquid sample position the
sample in front of the probe and adjust the position so that the liquid is ~9mm from the end of the
probe shaft (without distance regulator).

8. Turn the key to the in the back of the unit to the on position, turn the dial on the front of the control
box to the desired laser power (Note: the readout on the unit is in current, not power) and press the
laser enable button to turn on the laser inside of the probe.
Note that this laser is configured with a remote interlock. IPS has provided an RJ-11 (4-pin telephone jack)
that is pre-wired to provide a closed loop connection for the interlock. Removal of the RJ-11 connector or
break in the closed loop circuit provided will result in a laser interrupt and the system will be reset to
standby mode. Users may reconfigure the RJ-11 connector to provide a closed loop that interactively couples
with their system or facility by replacing the short length of wire with longer closed loop connections if
desired.

IIa. Laser Start-Up (External Power Control Mode)
Note: The laser unit is normally designed for operation by interacting with front panel controls, however
users may wish to modulate or adjust the output power of the laser module in some circumstances. The unit
is equipped with an external DC bias port located on the back panel of the module. The following steps
should be taken if the user wishes to control the laser output power remotely via a signal generator or
computer:
Caution—use of controls or adjustments, or performance of procedures other than those specified herein
may result in hazardous radiation exposure.
1. Ensure that the laser is not operating by pressing the laser ON switch and assuring that the laser on
LED is not illuminated.
2. Switch the mode selection switch located on the back panel to the “External” position (the Amber
operating mode LED labeled “External” will be illuminated).
3. Connect a BNC cable to the port labeled “Control” on the back panel. The user may apply a DC bias
between 0 and 1.0 V to modulate the laser or to adjust the laser’s output power. 0 V corresponds to
0 power, 1.0 V corresponds to full power. The unit can be modulated at rates up to approximately 1
KHz.
4. Turn on the laser by momentarily depressing the Laser On switch on the front panel. The laser will
now output a variable amount of output power that is dependent upon the DC bias voltage that has
been applied to the Control port on the back panel.
5. The unit can also be controlled via USB using our LCU software with a graphical computer interface
allowing the laser to be turned on and off. It also allows a percentage of the power to be set from 10
to 100%.The power is set by pulse width modulation (PWM) at around 1000 Hz.
III. Laser Shut Down
The following steps should be followed when shutting down the Laser Module.
1. Depress the Laser On button on the front panel and assure that the Laser On LED is not illuminated.
2. Turn the master power key switch on the back panel counter clockwise from the horizontal “On”
position to the vertical “Off” position.
3. Disconnect fiber patch cord and power cables as needed.
