Set Up 4: 10 mm Diameter Sleeve with multiple fibers aligned in a row
Install the 10 mm sleeve to the X-Y adapter and lock it into place by tightening
down the 3 set screws surrounding the adapter. Note the orientation of the fibers
in the sleeve of the fiber cable. Orient the fibers vertically and gently slide the
cable/fiber into the entrance of the fiber optic input assembly so the end of the
fiber adapter contacts the slits. Now pull the adapter back approximately .1 mm
so it is no longer contacting the slits. Verify that the fibers are aligned vertically
and then tighten down the set screw.
Alignment Procedure:
1. Adjust the vertical adjustment micrometer until the image of the fiber is
centered in the height of the CCD or the center of the exit slit.
2. Slowly reduce the entrance slit width to approximately the fiber core diameter
of the fiber while adjusting the horizontal adjustment micrometer to center the
fiber on the entrance slit for maximum signal.
Note: If the fiber bundle consists of a series of fibers aligned vertically, it may
be necessary to rotate the fiber to vertically align the fibers with the slit
during this procedure.
3. The fiber is now properly aligned.
