Aligning the focusing optics

1.1

Alignment of the focusing optics to
the processing plane

In order to get good processing results, the optical axis of the
focusing optics has to be aligned exactly vertically to the proc-
essing plane.

Reference surface

Workpiece

Fig. 112281

1. Align the reference surface vertically to the Y direction of the

processing plane.
