AREX™ 401
APPENDIX C
LASER SAFETY
The following information is provided in compliance with regulations set by Interna-
tional Authorities, and it refers to proper use of the laser marker.
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, Nd:YVO4 DPSS lasers) up to long infra-
red (e.g. CO2 lasers). It should be considered as non-ionizing Radiation.
In the Arex™ 401 laser marker, the laser radiation emission, at near 1 micron wave-
length 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 standard Q-switch or
Fiber MOPA fiber laser system installed 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™ 401 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.
Arex™ 401 laser markers are classified Class 4 according to applicable norms. This
means that the laser radiation level emitted by these laser markers is dangerous even
when not directly exposed to the laser beam. Partial reflected laser beam or scattered
laser radiation surfaces can cause damage to human eye and skin. It is therefore manda-
tory that customer apply all applicable regulatory safety protection measures when
integrating these laser markers into their machines including, but not limiting, to indi-
vidual operator protection devices such as protective eye goggles, etc.
In addition to possible injuries to human eye and skin, these lasers can ignite flammable
materials and cause fires even at long distances.
WARNING: Directly viewing a laser beam can cause irreversible damage to
human eye.
WARNING: Viewing of a reflected laser beam can cause irreversible dam-
age to human eye. The use of accessory external optics may increase the
risk of damage.
