PerkinElmer RamanMicro 300 Series Getting Started Manual page 19

When using the microscope, the following precautions must always be observed:
• 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;
• Place warning signs near the laser operating areas;
Control laser areas and limit access to individuals trained in the safe operation of lasers;
•
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);
• Use an interlock switch on the door to the laboratory, if required.
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;
WARNING •
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.
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
WARNING
covers are in place when FOPs are not in use.
