When using the fiber optic probe, the following precautions should be observed:
• Never look directly into the laser beam or at the laser light scattered from a reflective
surface.
• Avoid direct exposure to the laser light.
•
Use an interlock switch on the door to the laboratory and/or the reaction vessel.
•
Place 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).
•
Ensure that the attenuator cap is attached.
Triggered Fiber Optic Probe Safety
When attached to the RamanMicro 200, a triggered fiber optic probe (TFOP) provides a
focused beam of Class 3B laser radiation. During normal operation, laser radiation is
accessible from the end of the probe.
The following precautions must be observed at all times:
• Keep the protective cover in place on the probe tip when the probe is not in use.
If you are using the TFOP with a plastic spacer, always rotate the spacer so that the
screw is beneath the probe barrel when not in use; when in this position the spacer acts
as a lens cap.
•
Never look directly into the laser beam or at the laser light scattered from a reflective
surface or sample. Permanent eye-injury may result. Do NOT attempt to examine the
probe tip when the Path Active light on the probe is lit.
• Post warning signs near the laser operating areas.
