Laser Safety - Scanlab hurrySCAN 10 Installation & Operation Manual

3.2 Laser Safety

This scan head is designed to be operated in conjunc-
tion with a laser. Therefore, all applicable rules and
regulations for safe operation of lasers must be
known and applied when installing the scan head
and operating the system in which it is used. Since
SCANLAB has no influence over the employed laser or
the overall system, the customer is solely responsible
for the laser safety of the entire system.
!
Danger!
• Safety regulations may differ from country to
country. The customer bears sole responsibility
for compliance with all applicable safety regula-
tions of their respective regulatory jurisdiction.
Shutter
The scan head has no shutter and there is no device
to decrease the laser output power. It is the responsi-
bility of the customer to include such a device in the
system in a way as to comply with all regulations. The
observance of laser safety must be ensured for the
entire system.
Maintenance
During maintenance of the laser equipment, the class
of the laser can increase. Therefore, the customer
must take suitable protective measures.
Warning Symbols
The area where the emerging beam is harmful must
be marked with a warning symbol indicating the class
of the employed laser – in accordance with IEC
60825-1 laser safety requirements. In addition, a
warning symbol must be placed at the emitting aper-
ture of the laser system. The table on
the appropriate warning symbols for the various laser
classes specified by IEC 60825-1 (or EN 60825-1 / VDE
0837 T1).

3 Safety During Installation and Operation
!
• During assembly or operation of the scan head,
never stare directly into the laser beam or its
deflected radiation. Keep all parts of the body
away from the laser beam and its path. Routine
maintenance should be performed as described
in "Routine Maintenance of the Optical Surfaces"
on page 31
observed!
• Adjust the output beam path of the scan head
by means of a Class 2 laser. If this is not possible,
the laser should be operated at the lowest
power. Avoid dangerous deflected radiation!
• The risk of hazardous deflected radiation can
increase when optical instruments are used in
combination with the scan head.
• Before checking the scan head, make absolutely
certain that the laser and scan head are turned
off!
• Cover the path of the laser beam via an appro-
priate protecting case to block laser radiation!
• Do not obstruct the movement of the scan
head's mirrors in any way. When the scan head
is turned on, the mirrors must not be touched at
all!
• Closely follow all IEC 60825-1 laser safety
requirements and other applicable accident
prevention regulations of your respective regu-
latory jurisdiction.
• Wear appropriate eye protection at all times.
• Always turn on the PC controller and the scan

head's power supply first before turning on the
laser. Otherwise the laser beam might be
reflected in an arbitrary direction.
