64 . RamanFlex 400 Series Getting Started Guide
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.
NOTE: If you have purchased a RamanFlex 400F you can attach two fiber optic probes to
the couplers on the rear panel of the spectrometer module.
Attaching the FOP
1. Ensure the attenuator cap is attached to the FOP.
2. Turn off the instrument and remove the main power cable.
3. Carefully move the spectrometer module to permit easier access to the rear panel.
4. Remove the retained screw-in caps from the two couplers at the bottom left of the
panel.
If you have a RamanFlex 400F and wish to connect a second fiber optic probe, remove
the retained screw-in caps from the two couplers below the LED FIBER 2 connector.
5. 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 15).

6. 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.
7. Connect the plug to the nearby socket marked LED FIBER 1.
If you have a RamanFlex 400F and are connecting a second fiber optic probe, connect
the plug to the socket marked LED FIBER 2.
8. Reconnect the power cables.
