AutoLas Plus function
The AutoLas Plus mirror serves to compensate the focus shift and
the program-controlled setting of the focus position.
The surface of the AutoLas Plus mirror is intentionally reshaped by
the pressure of the cooling water. As a result, the angle of
divergence of the laser beam is adjusted in such a way that it is
possible to shift the focus systematically upwards or downwards
during machining. During machining, the focus position is
automatically modified via the AutoLas Plus mirror without manual
intervention.
The AutoLas Plus system is controlled via characteristic curves.
Each lens focal length is assigned two characteristic curves. They
are assigned automatically via the AutoLas Plus characteristic
curve parameter in the "General" laser technology table.

AutoLas Plus characteristic curves, cutting head
The setting range within which the focus position can be
automatically adapted depends on the following:
•
The focal length of the installed lens.
•
The AutoLas Plus characteristic curve.
The following table contains recommended values:

adjustment range Focus position
range from ... to
5" cutting head 6.2 mm +1 mm to -5.2 mm
7.5" cutting head 14 mm +4 mm to -10 mm
Recommended values for the automatic adjustment
range
The actual values are machine-specific and are determined when
the machine is put into service by measuring the beam and then
stored as machine parameters.
