Replacing the Laser Head and adjusting the Fibre Coupling
The Fibre can not be uncoupled from the module,
but only from the Laser head.
Purpose of the adjustment:
Optimising the laser capacity by adjusting the fibre
coupling on the laser head.
Elements of the adjustment unit:
− Fibre holder (1): Tube into which the fibre end is
put
− Adjustment screws (2):
4 knurled screws, Allan screws (size 2)
Always 2 screws are used for the horizontal and
the vertical direction. The screws are locked with
spring-loaded knurled nuts. The lock nuts should
be tightened slightly for the adjustment so that
the adjustment screws are pretensioned.
Caution: Fine thread
− Pressure screws (3):
2 screws with a flat head and a spring-loaded
Nylon tip are used for the fastening of the fibre in
the adjustment unit. The screw on the laser side
holds the fibre holder in the adjusted lateral
position, the screw on the exit side fastens the
lengthwise position of the fibre holder.
− Fastening ring (4, no fig.) for the polarisation
adjustment (must not be unscrewed!)
− Allan screw (5), size 2
