Attaching and Removing the Fiber Optic Probe
The standard fiber optic probe is constructed such that a single armored cable bifurcates into
an excitation cable and a collection cable. The excitation fiber transmits the laser energy,
whereas the collection cable is a conduit for the Raman energy. Both fibers terminate in FC
style connectors. There is also a plug attached to the end of two wires which connects the
fiber optic LED to the instrument.
Attaching the FOP
1. Ensure the attenuator cap is attached to the FOP.
2. Turn off the instrument and remove the main power cable and, if appropriate, the stage
controller power cable.
3. Carefully move the instrument to permit easier access to the rear panel.
4. Remove the fiber port cover assembly if fitted (see
Attaching the Fiber Port Cover
Assembly
on page 49).
5. Remove the retained screw-in caps from the coupler area at the bottom left of the
panel.
6. Connect the excitation cable of the FOP to the coupler marked EXC.
Make sure that the polarizing ridge on the FOP cable is aligned with the slot in the
coupler casing before carefully pushing the cable into the coupler (Figure 27).

7. Connect the collection cable of the FOP to the coupler marked COL.
Make sure that the polarizing ridge on the FOP cable is aligned with the slot in the
coupler casing before carefully pushing the cable into the coupler.
8. Connect the plug to the nearby socket marked LED FIBER #1.
9. Reconnect the power cables.
