Laser Shutter
A laser attenuator (beam shutter) is a mechanical or electrical device that blocks the emission of
laser radiation. It is a requirement for most classes of laser systems. The attenuator must be
available for use at all times when the laser system is operated. Power switches and key controls do
not satisfy the attenuator requirement.
The AGV-HP(O) scan head does not include a laser attenuator, and therefore it cannot block or
weaken the laser beam. Due to the unique properties of each laser, it is the responsibility of the user
to incorporate an appropriate shutter as per any and all applicable regulations in order to prevent
unwanted emission of the laser beam.
Place the beam shutter between the laser source and the scan head (refer to Figure 1 ).
DANGER : The danger to your eyes increases when optical instruments are used in
conjunction with the scan head.
l
Wear certified laser safety eye protection.
l
Do not stare into the laser beam, put your body parts in the laser area, or expose
yourself to reflections from powerful beams.
WARNING : Aerotech recommends that you only use a Class 1 HeNe laser to do
alignments. If a Class 1 HeNe laser is not available, use the lowest power setting on the
available laser and remote beam sensing techniques.
