DEGREE OF RISK WITH RADIATION VIEWING CONDITIONS
USER MANUAL
101
Viewing of a laser reflected beam
This may occur when beam is reflected on a mirror surface. This type of viewing is as
danger for human eye as direct viewing of the laser beam.
Viewing of direct laser beam from a fiber output
Although unlikely to happen since fiber is protected by an armored stainless steel cable,
this may occur when the optical fiber cable, that connect control rack with resonator is
damaged and fiber is broke. The laser radiation is highly divergent but power and
energy is high and risk is similar to direct viewing of a laser beam.
Viewing of scattered laser beam
This is the most typical exposure condition when laser is scattered by at a non-reflective
surface (such as blocking element or when marking of some materials). In this case, spe-
cial filter widows and Individual Protective Devices (such as goggles) may allow full pro-
tection even for prolonged exposures if is such protective means respect applicable
norms for the type of laser radiation.
WARNING
Do not look to reflected laser beam. Individual Protection Devices such
goggles may only provide protection for a short period of time and thus do
not warrant protection for exposure to reflected laser radiation.
WARNING
Many materials, including metals and plastics, have surfaces that strongly
reflect laser radiation. Make sure to use non-reflective materials for
enclosures or any other machine surfaces that may be exposed to direct or
indirect laser beam radiation. Pay special attention when marking objects
with high reflectivity properties.
WARNING
Do not look to fiber output laser beam. Individual Protection Devices such
goggles may only provide protection for a short period of time and thus do
not warrant protection for exposure to direct laser radiation.
WARNING
Always use certified protecting goggles appropriated for the laser radiation
characteristics to which you can be exposed.
WARNING
Remember that none goggles can provide sufficient protection for pro-
longed direct or reflected laser beams.
