3. Move the Beam Profiler, measure the distance again, enter the new distance into the box
"Position 2" and press the 2nd icon.
4. The beam width at Position 2 is calculated and based on the entered distance change, the
vergence angle in X and Y axes is displayed.
Note
The accuracy of the entered distance between the two positions (shift) of the Beam Profiler is
significant for vergence measurement accuracy.
Hint
If you are using the Beam Profiler together with a M2MS Extension Set, the Manual Vergence
measurement is even more simple:
· Remove the focusing lens from the system.
· Feed the laser beam into the M2MS-BC207 Series input aperture and align it.
·
Open in the Beam Settings panel the Translation Stage Control topic.
·
Use the stage slider to set 0 and 200 mm positions and proceed as described above.
