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 on page 23.
Fiber Optic Probe Safety
The fiber optic probe body incorporates a number of important safety features, including:
• Beam attenuator/cover
• Emission Indicator/LED
When attached to the spectrometer, the fiber optic probe provides a focused beam of class
3B laser radiation. During normal operation, laser radiation is accessible from the end of the
fiber optic probe. The LED emission indicator (Figure 1) at the probe head is configured so
that the LED lights up when the laser is turned on, indicating that laser radiation is emitting
from the probe aperture. The LED emission indicator is visible through laser safety goggles.
To avoid unnecessary exposure, the output energy should be enclosed whenever possible
(using a beam attenuator or cover). The laser should also be turned off and the probe
covered when the system is not in use. AVOID DIRECT EXPOSURE TO THE BEAM.

When using the fiber optic probe, the following precautions must always be observed:
•
Use an interlock switch on the door to the laboratory and/or the reaction vessel being
used in association with the fiber-optic-probe-based Raman spectrometer.
• Never look directly into the laser beam or at the laser light scattered from a reflective
surface.
• Avoid direct exposure to the laser light.
•
Post warning signs near the laser operating areas.
•
Controlled access areas, limited to individuals trained in the safe operation of lasers, are
suggested for laser operations.
• Use protective laser safety goggles, with an OD (optical density) of at least 3 at 785 nm,
as a precaution against accidental exposure to the direct or reflected laser light. Suitable
goggles are available from PerkinElmer (part number L1323518).
