Equipment Set for Wave Optics with Laser U17303
Instruction sheet
10/08 Alf
1. Safety instructions
The laser emits visible radiation at a wavelength of
635 nm with a maximum power of less than 1 mW,
thus conforming to class 2 regulations as specified
in DIN EN 60825-1 "Safety of lasers", i.e. the human
eye can be protected by the instinctive reaction to
turn away and blink.
•
Do not look straight into the laser beam or any
reflected beam.
•
Lasers should only be operated by trained and
authorised personnel.
•
All those people participating in or observing
an experiment must have been informed of the
dangers inherent in laser radiation and edu-
cated regarding protective measures.
•
Experiments may only be performed using the
minimum power output required in each spe-
cific instance.
•
Ensure that the beam is not directed at eye level.
•
Use suitable screening to isolate the area around
the laser and avoid unwanted reflections.
•
Any rooms in which laser experiments take
place should be labelled with warning signs.
•
Observe the regulations valid in the respective
country where the experiment is being per-
formed, e.g. Germany's health and safety regu-
lations BGV B2 "Laser radiation", and any
stipulations set by the relevant ministry.
Safe operation of the laser is guaranteed, provided
it is used correctly. However, there is no guarantee
of safety if the equipment is used in an inappropri-
ate or careless manner. If it is deemed that the
equipment can no longer be operated without risk
(e.g. visible damage has occurred), the laser should
be switched off immediately and secured against
any unintended use.
•
Before putting the equipment into operation,
check for any signs of damage. In the event of
any malfunction or visible damage, turn off the
laser and put it away so that it cannot be used
unintentionally.
•
Never open the housing.
