6.3.7.8 Live Adjustment
Open the Live Adjustment panel and click "start" to move the M2 stage to the lense focus plane
as calculated from the inserted parameters. Now, the laser system can be adjusted and, for ex-
ample, collimation can be optimized until the beam width in the focus plane is minimized.
As the stage moves to the focal plane, the Z-slider on the bottom right moves under the lens fo-
cus (LF) icon.
The right panel shows the Beam Width and Centroid Position in X and Y.
Beam Width : The displayed beam width is calculated based on the settings chosen in the Set-
tings Panel of this window opened through the icon on the left.
Centroid Position : The Centroid position is displayed to maintain knowledge of the beam posi-
tion during adjustment.
Adjustment in Z is facilitated by the slider on the bottom right.
