Using the RamanMicro 200 Series . 59
Fiber Optic Probe
NOTE: This section is only applicable if you have a RamanMicro 200F that is fitted with a
fiber optic probe.
NOTE: For details of how to use a triggered fiber optic probe, see the
Raman Triggered
Fiber Optic Probe
leaflet (L1321940).
General Overview of the Fiber Optic Probe
The fiber optic probe (FOP) is designed to enable the remote measurement of samples. It is
available in a range of different configurations, depending on the end-user’s application.
However, it should be noted that compatibility of the working environment with the probe
should be verified with PerkinElmer prior to use.
The probe body contains the filtering optics and is interfaced with two fiber optic cables (an
excitation fiber and collection fiber). Care should be taken when handling the probe body so
that the optical window is not soiled or damaged.
NOTE: If you use the probe body in any chemical or aggressive environment you must use
an immersion sleeve to protect the probe body. DO NOT ATTEMPT TO USE THE
PROBE BODY IN SUCH AN ENVIRONMENT WITHOUT THE USE OF AN
IMMERSION SLEEVE (L1320003). If required, contact PerkinElmer for further
details.
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. If you have a standard probe, there is also a DIN connector attached to the
end of two wires which connects the fiber optic LED to the instrument. If you have a
triggered probe, there is an Ethernet cable that connects to a USB extender which connects
the probe to the PC.
Attaching the FOP
1. Ensure the attenuator cap is attached to the FOP.
2. Turn off the instrument and disconnect the main power cable and, if appropriate, the
stage controller power cable.
3. Carefully move the spectrometer module to permit easier access to the rear panel.
4. Remove the two retained screw-in caps from the two coupler ports marked EXC and
COL below the FIBER 2 connector on the rear panel (Figure 27).
