LASER RADIATION
Laser radiation is an electromagnetic emission with a micrometric wavelength which ranges from the long
infrared (CO
2
Laser), close infrared (Yd fiber, Nd:YAG, Nd:YVO
4
), visible (He:Ne or Argon) and ultraviolet
(excimer laser).
It should be considered non-Ionizing Radiation. In Arex
TM
marking system, the emission of a light is
stimulated by “optical pumping” generated by a Diode Laser. The continuous reflection of Photons, between
a front mirror and rear mirror, creates a positive reaction so that their number continues to increase, until
reaching the concentration necessary to produce a beam which projects from the semi-reflecting front mirror.
The radiation (which we can imagine as a “Beam of invisible light”) is then Collimated and Focalized with
Lenses at a point where the intensity becomes high enough to be able to react with various materials
producing an alteration in them due to thermal effect.
The radiation of Arex
TM
marking system is invisible and the Eye receives it almost in its entirety without using
the natural defense provided by pupil reflex! Added to this is the fact that it is generally very intense, with the
result that it can be very harmful to the eye and present vision problems.
WARNING!
Directly viewing a laser beam can cause irreversible damage to vision.
To prevent permanent damage to vision, a few precautions must be taken.
All individuals who may be exposed to dangerous levels of laser radiation, must know that the laser is active
and wear protective goggles if necessary.
Due to its high power, the laser integrated in the Datalogic system provokes reflected laser light from flat
surfaces. Reflected light is potentially dangerous for the eyes and skin. Electromagnetic emission with a
micrometric wavelength is placed in long infrared, and is therefore invisible, thus it is not clear where
reflected beams are aimed.
WARNING!
It is indispensable to protect yourself from reflected light beams , because they can be
sufficiently intense to create permanent injury to the eyes or skin.
In addition to possible injury to the eyes or skin, direct laser emission can cause flammable materials to burn
like organic solvents (alcohol, acetone) or gasoline and cause fabric and clothing to burn.
WARNING!
This marking system is classified as Class 4 . Class 4 includes lasers which can produce risks, not
only from direct or reflected radiation, but also from scattered radiation! The laser sources may be
a significant risk for the skin and risk of burning flammable materials.
