Laser Beam Input Unit: Four are standard. Can be increased optionally to six.A laser
beam input unit focuses the laser beam into the attached fiber optic cable. The laser
beam input units are numbered from 1 to 6, from the front to the back of the laser.
Branch Shutter: There are six branch shutters. Each one is associated with an
equivalently numbers laser beam input unit. The branch shutters are opened to select
their associated laser beam input units for output of the laser beam. Like the laser beam
input units, the branch shutters are numbered from 1 to 6, from the front to the back of
the laser.
