20 . RamanStation 400 Series Getting Started Guide
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. The output energy should be enclosed whenever possible (using a
beam attenuator/cover) to avoid unnecessary exposure. The laser should also be turned off
and the probe cap replaced 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 when
you are using a fiber optic probe.
•
Never look directly into the laser beam or at the laser light scattered from a reflective
surface or sample.
•
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 (L1323518).
