TIP
Perform this procedure only when testing the settings, as described in subsection 6.7.6
on page 56 and if the
hole’s entr
y is round, but its exit is elliptical.
The laser beam’s polarization can be set by 2 levers at the respective unit inside the scan
head.
In order to measure the polarization and thus to set it, we recommend a polarization
meter, e. g. Glan Thompson. Use the polarization meter according to the respective
manual.
Tools
• Laser safety glasses appropriate to the laser in use
•
Hexagon socket screw key, AF 1.5 mm
• Glan-Thompson polarization meter
Requirement
•
The nozzle including the protective glass has to be mounted to the scan head.
