2.
Refer to 8-9. While monitoring the end surface of the optical fiber through the
fiberscope, adjust the X - Y axes adjustment screw so that the guide beam comes
to the center of the end surface. The beam on the left is the rear reflection beam
from the branch mirror. Do not confuse the beam with the guide beam on the
right.
3.
Tighten the lock nut and the X - Y axes adjustment screw. Look
into the fiberscope and verify that the direct guide laser beam is
located at the center of the fiber end face.
