PRECESSION ELEPHANT 2 Scan Head 2
CAUTION
Visible or invisible laser radiation during commissioning
could cause damage to eye or skin.
•
Wear protective glasses that are appropriate for adjusting your laser.
•
Avoid eye or skin exposure to direct or scattered radiation.
•
Parametrize the laser for visual set up with average power and pulse repetition
rate as low as possible.
Protective goggles
The mandatory protective glasses provide protection against direct radiation,
reflected radiation and scattered radiation. None the less, even if you are
wearing protective glasses never look directly into the beam or into a reflected
beam. Intense laser radiation is capable of destroying the protective filter.
If alignment or maintenance work on class 4 laser equipment is necessary,
everyone in the laser area has to wear appropriate protective glasses. The glasses
have to meet the safety requirements for the laser output power in question.
As the filter in the protective glasses only provides protection for a narrow band
of wavelengths, make sure you are wearing the right glasses for the laser device
in question. Using the wrong type of protective glasses is dangerous. The most
commonly used protective glasses for CO
2
lasers do not, say, protect against the
radiation from an Nd:YAG laser.
•
Before putting on the protective glasses check them for any obvious
defects. If any of the following defects occur then use protective glasses
that are undamaged:
o
Fissures on the protective filter
o
Scratches on the protective filter
o
Modifications in color
o
Modifications in the light permeability
o
Loosen screws
o
Cracks in the frame
