Safety Practices . 21
WARNING
Do not make any adjustments to the microscope or any part of the
system when experiments are in progress.
In particular:
•
Do not remove the objective lens from the microscope
•
Do not insert or remove samples
•
Do not disconnect the Raman module
•
Do not fit binocular eyepieces to the microscope module.
These adjustments may deflect laser light from the safe light path
through the system.
WARNING
Do not leave blank positions in the microscope turret when performing
your experiments. Ensure that all blank positions have protective covers in
position at all times.
If your system includes any Fiber Optic Probes, ensure that protective
covers are in place when FOPs are not in use.
Fiber Optic Probe Safety
NOTE: This section is only applicable to RamanMicro 200F systems equipped with a fiber
optic probe.
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 2) 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 or cover) to avoid unnecessary exposure. The laser should be turned off
and the fiber optic probe attenuator cap replaced when the system is not in use. AVOID
DIRECT EXPOSURE TO THE BEAM.
