6. Install the optional colored filters into the filter slide as shown in Figure 2 using the filter wrench
provided, or a spanner wrench, to tighten the retaining rings. Do not over tighten, as this will
damage the filters.
Note that the filter slide must have at least one of the filter locations left open (without a filter)
when white light biasing is required. Leave the retaining ring installed so that it does not get
misplaced.

7. Install the filter slide into the filter assembly, taking care that it is oriented exactly as shown in
Figure 3. The filter slide must be installed even if only white light biasing is desired, to prevent
light leakage.
8. Affix both 77646 beam probes onto the two legs of the 77533 fiber bundle. Refer to the
instructions provided with the beam probes. Ensure that the set screws on the beam probe
bodies are backed out far enough so as not to interfere with the fiber insertion and possibly cause
damage to the end face.
9. Install the common end of the fiber bundle into the filter slide and tighten the retaining screws,
after ensuring that the screws on the filter holder are backed out far enough so as not to interfere
with the fiber insertion and possibly cause damage to the end face.
10. Install each leg with its beam probe into the mounting adapter holders. Tighten the set screws [C]
as shown in Figure 1 to secure the fiber.
