VLASE™ IR
LASER RADIATION
Laser radiation is an electromagnetic emission with a micrometric wavelength which
ranges from the long infrared (CO2 Laser), close infrared (Nd Laser: Yag, Nd: YVO4), visi-
ble (He Laser: Ne or Argon) and ultraviolet (excimer laser).
It should be considered non-Ionizing Radiation. In the Vlase™ laser marker, the emission
of a crystal bar is stimulated by "optical pumping" generated by a Diode Laser. The con-
tinuous 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 radiations of the Vlase™ laser marker are visible and 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.
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 wave length is placed in long infra-
red, and is therefore invisible, thus it is not clear where reflected beams are aimed.
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 damage to human
eye. The use of accessory external optics may increase the risk of damage.
WARNING
This laser marker is classified as Class 4. Class 4 Lasers can cause dam-
age, not only from direct or reflected laser radiation, but also from scat-
tered 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.
WARNING
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.
