1.2.1 Safety Information
The light source of the instrument is a laser. It is important to understand that
laser light has different properties from ordinary light sources. Laser light is
generally extremely intense due to the beam's low divergence. When
handling lasers, great care should be taken in any case to make sure that the
direct or reflected beam does not enter the eye.
NOTE!

General
The protective measures described in the following support compliance with
the safety standards for
Laser Class 2
:
•
Polytec instruments generally comply with the standards
IEC
and
EN 60825-1
respectively
US 21 CFR 1040.10
and
1040.11
except for
deviations pursuant to Laser Notice no. 50, dated 24 June 2007.
•
The optical output power of the laser beam emitted from the instrument is
less than 1mW provided the equipment is used in the manner for which it
was intended. This means that the instrument conforms with
laser class 2
and is generally very safe. It is thereby usually assumed that eyes are
protected by prevention mechanisms including the blink reflex. This
reaction offers appropriate protection under reasonably foreseeable
operating conditions. This includes the use of optical instruments for
observing the laser beam. Even when optimally focused, the laser beam
is not intense enough to harm the skin.
•
The user should not attempt to open the housing of the instrument which
contains the laser unit as he could be exposed to a higher level of laser
radiation that is potentially hazardous.
•
Use of controls or adjustments or performance of procedures other than
those specified here may result in hazardous radiation exposure.
Specific
•
An
emission indicator
on the scanning head indicates the activity of the
installed laser and thus the potential hazard of laser beams emitted.
•
The laser is switched on using the
key switch
on the front-end. The key
can only be removed if the front-end and therefore also the laser is
switched off.
