AutoLas Plus is a mechanism for automatic, program-directed
adjustment of the focus position to suit the type and thickness of
the material according to the laser technology table, and for
compensating the focus shift

on laser machines across the whole
working range. The advantages of AutoLas Plus are as follows:
•
The focus position no longer has to be set manually within the
automatic setting range which is possible with AutoLas Plus.
•
The focus position specified in the technology table is set
automatically resulting in operating errors being excluded to a
great extent.
•
The focus position is automatically adjusted to the respective
material thickness and type.
•
While a program is running the focus position can be varied
automatically, making it possible to optimize the process.
•
The focus position is kept nearly constant over the whole
working range - independent of the beam length.
The central component part is the adaptive mirror whose surface is
intentionally shaped by the cool-water pressure. 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.
