10)
Turn the laser on to ensure that beam is aligned through the center of the iris on the output port
of the KCB1 and along the cage structure using the VRC4CPT as previously illustrated in Figure
6.1.1. Remove this KCB1 with mirror and put it aside as it will later be used for the coupling to
the vertical path of the microscope.
11)
Use a second KCB1 with a second mirror, PF10-03-P01 and align in the same way as in steps
10-12 above. The completed model is shown in Figure 6.1.2.

1.
Mount a CP02 onto a CPB1.
2.
Mount the achromatic doublet ACN254-050-B into an SM1V10 lens tube and thread it into the
CP02 (from the previous step), such that external retaining rings on the SM1V10 are on both
sides of CP02. Make sure that the lens is mounted in the lens tube so that the collimated beam
from the FiberPort is incident on the curved surface of the doublet.
3.
Connect an SM1T2 to the KCB1 from the previous section. Get a couple of threads into the
KCB1 and lock to the KCB1 using one of the locking rings on the SM1T2.
4.
Attach the SM1V10 from step 2 to the SM1T2 and lock these together using the other locking
ring on the SM1T2.
5.
Thread an SM1L10 on the other side of the CP02 holding the SM1V10 and first lens. The lens
tube will thread into the SM1V10 also. The SM1L10 should touch the other face of the CP02 as
shown in Figure 5.2.1.
6.
Clamp the CPB1 attached to the CP02 to table using the miniature rail clamp CL6.
7.
Attach another SM1L10 to a new CP02.
