Laser radiation
Laser radiation is form of electromagnetic emission in the wavelength range
from the ultraviolet (e.g. from excimer lasers), through visible (e.g. HeNe or
Argon lasers) and near infrared (e.g. Yb Doped Fiber and ND:YAG DPSS lasers) up
to long infrared (e.g. CO2 lasers). It should be considered as non-ionizing Radi-
ation.
In the Arex™ 400 laser marker, the laser radiation emission, at near 1 micron
w
avelength range, is obtained thought a diode optical pumping of an Yb doped
rare earth doped pulsed fiber laser. Depending on the model, the laser is a stan-
dard Q-switch or Fiber MOPA fiber laser system ins
talled at the control rack. The
laser optical radiation is delivered to the scan head through an armored fiber
cable (inside the Head cable), and an isolated beam delivery optical system
(IBDO). The laser beam exiting the IBDO is a collimated laser beam that is then
processed inside the Scan Head through an optical scan system and F-Theta
scan lens to scan and focus the laser beam at the marking plane.
The radiation of the Arex™ 400 laser marker is therefore invisible to human eye
and
thus not blocked by the natural pupil reflex and can result is severe damage
to human eye and skin.

Directly viewing a laser beam can cause irreversible damage to human eye.
Arex™ 400 laser markers are classified Class 4 according to applicable norms.
This means that the laser radiation level emitted by these laser markers is dan-
gerous even when not directly exposed to the l
aser beam. Partial reflected laser
beam or scattered laser radiation surfaces can cause damage to human eye and
skin. It is therefore mandatory that customer apply all applicable regulatory
safety protection measures when integrating these laser markers into their
machines including, but not limiting, to individual operator protection devices
such as protective eye goggles, etc.

Viewing of a reflected laser beam can cause irreversible damage to human eye. The
use of accessory external optics may increase the risk of damage.
In addition to possible injuries to human eye and skin, these lasers can ignite
flammable materials and cause fires even at long distances.

Make sure that no flammable objects/materials are within the laser beam path. Use
only non-flammable materials for enclosures or any other machine surfaces that may
be exposed to direct or indirect laser beam radiation.
This laser marker is classifie
d as Class 4. Class 4 Lasers can cause damage, not only
from direct or reflected laser radiation, but also from scattered radiation. These lasers
cause significant risk of irreversible damage to human eye and skin as well as risk of
ignition and fire of flammable materials, even at long distances form laser radiation
output aperture.
