1.2 Information on Laser Safety
1.2.1 Safety Information
The light source of the instrument is a helium neon laser. It is important to
understand that laser light has properties different from ordinary light sources.
Laser light is generally extremely intense due to the beam's low divergence.
Great care should be taken when handling lasers that the direct or reflected
beam do not enter the eye.
NOTE!
Please see
CHAPTER
7 for the detailed technical specifications!
The protective measures are 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 or US 21 CFR 1040.10 and 1040.11 respectively except for
deviations pursuant to Laser Notice No. 50, dated 24 June 2007.
•
The optical output power of the laser beam emitted from the sensor head
is less than 1 mW provided the equipment is used in the manner for which
it was intended. This means that the instrument conforms with the laser
class 2 and is generally very safe. It is thereby usually assumed that the
eyes are protected by prevention mechanisms including the blink reflex.
This reaction offers appropriate protection under reasonable 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 instrument is equipped with a beam shutter to block the laser beam
during the warm-up phase or when the vibrometer is not in use, although
switched on.
•
An emission indicator on the instrument signalize the activity of the
installed laser and thus the potential hazard of laser beam emitted.
•
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
energy that is potentially hazardous.
WARNING!
Danger from uncontrolled light emission ! Use of controls or adjustments or
performance of procedures other than those specified herein may result in hazardous
radiation exposure.
