Degree of risk with radiation viewing conditions
User Manual 97
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.

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.
Do not look to reflected laser beam. Individual Prot
ection 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.
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 Cable Head, that connect control rack with scan
head 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.

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.
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, special filter widows and Individual Protective Devices (such as gog-
gles) may allow full protection even for prolonged exposures if is such protective
me
ans respect applicable norms for the type of laser radiation.

Remember that none goggles can provide sufficient protection for prolonged direct or
reflected laser beams.
Always use certified protecting go
ggles appropriated for the laser radiation character-
istics to which you can be exposed.
