Overview
The Fiber laser marker developed and manufactured by Datalogic employs the
most advanced technologies with regards to the opto-mechanical parts, the
electronic control of laser beam power, communication and the overall safety of
the entire marker.
Laser Source
On Arex™ 400 laser marker it is used a sealed fiber laser source. This source is
based on the new fiber solid state technology. It guaranties high stability, lower
sensitivity to optical misalignment and a longer product lifetime.
Galvanometric scan head
The scan head features two deflection mirrors that deflect the beam in X and Y
directions, depending on the graphics/pattern to be reproduced.
Operation of a laser marker with galvanometric scanning
During the marking the laser generates an invisible, high-energy infrared beam.
In order to obtain a more accurate focus,
the laser beam is first enlarged using
an optical expansion system and then deflected by a scanning system consisting
of two mirrors mounted on galvanometric motors.
These mirrors deflect the beam in a controlled path along the
X and Y axes; pro-
cessing of the product surface occurs by coordinating the movement of the two
m
irrors and the turning on/off of the laser beam.
The deflected laser beam is focused by an F-Th
eta scan lens on the surface of
the product.
Generally speaking, the marking is carried out within the focus plane of the F-
Th
eta scan lens.
Marking Software
The Ligther™ marking software is preinstalled on the product.

ARNING
It is the responsibility of the customer to install the laser marker in proper safety con-
dition!
If necessary, consult “How to update the marking software” on page 118, to upgrade
the preinstalled software.
Consult Lighter™ software user's manual for a prope
r use of the same.
