WARNING!
CAUTION!
Welding Camera is a class 3R laser system
o
laser class is indicated by the warning label on top of the camera unit (see the
label above)
o
laser aperture is indicated by the yellow aperture label on top of the camera
unit (see the label above)
o
Nominal Ocular Hazard Distance (NOHD) is 3 meters
Do not look into the direct, reflected or scattered laser beam
o
camera unit emits visible red laser light at 645 ± 10 nm wavelength band
o
laser beam is emitted from the front of the camera unit (from the mirror-like
window in Fig. 3.3). The beam spreads in such a way that it covers the field-
of-view of the camera (~30 mm x 40 mm) at the design working distance (200
mm)
o
use of appropriate laser safety goggles is recommended for eye-safe operation.
Suitable laser safety goggles must have an optical density of at least 3 (OD3) at
the wavelength band 645 ± 10 nm
The accidental exposure to direct/reflected/scattered laser beam has to be prevented:
o
train personnel not to stare at the laser output
o
pay special attention to possible bystanders or persons passing by
