Class 3B Safety Precautions
When using the fiber optic probe you should follow Class 3B laser safety precautions such as
wearing laser safety goggles and using door interlocks. For information on these precautions
please refer to an appropriately trained laser safety officer within your own facility. Laser
safety is very important. Inappropriate use of laser-emitting devices may result in permanent
injury. In the United States the precautions are described in the ANSI Z136.1-2000 Standard.
For information on the ANSI Z136 standard please consult your laser safety officer and/or
consult http://www.z136.org. Outside the United States the guidelines are described in
PD IEC TR 60825-14 (Safety of laser products ̵ Part 14: A user’s guide). You should also be
familiar with the guidelines published by the national authorities in your country.
The following information is provided as a general overview only. This information is
rudimentary and is supplied to assist in the interpretation of this manual. Under no
circumstances use this information as the basis of a laser safety code of behavior:
1. Class 3B lasers may emit visible and/or invisible radiation up to a maximum of 0.5 W
continuous wave (CW is longer than 0.25 s). They present a hazard to the eye if the
direct beam or spectral reflections are viewed without appropriate protection. You must
only operate Class 3B lasers in a designated area.
2. You must fit each Class 3B device with a captive key control switch, such that the key
cannot be removed from the lock except in the OFF position. The key should be
removed from the laser when it is not in use and kept in a safe place in the custody of a
nominated person. Keys must never be issued to unauthorized persons.
3. Each Class 3B device should be assessed by a suitably trained laser safety officer to
determine the accessible radiation emitted by the device. The laser safety officer should
consider laser power, wavelength and beam divergence when determining if the Class
3B device’s remote interlock connector should be connected to an interlock switch at
the entrance. For certain laser systems, the laser safety officer may require the shutter
to be interlocked with the laboratory entrance in order to prevent inadvertent exposure
of persons entering to very hazardous laser radiation.
4. Rooms in which Class 3B devices are used should have notices affixed to the doors so
that they conform to the requirements of appropriate Laser Safety Regulations.
If you have a fiber optic probe then please refer to

operating distances when using the fiber optic probe.
General Laser Safety Issues
Laser Keyswitch
There is a captive laser key control switch on the rear panel. This key is required to operate
the laser. A laser safety officer or laboratory manager should control the use of this key.
Laser Warning Labels
Laser warning labels are attached to the instrument for your safety. Please observe the
necessary precautions. For more details see
Warning Labels
