How to clean optical devices which are sensitive to mechanical stress and
pressure
46
Some optical devices, such as the Agilent 81000BR Reference
Reflector, which has a gold plated surface, are very sensitive to
mechanical stress or pressure. Do not use cotton swabs, soft
tissues or other mechanical cleaning tools, as these can scratch
or destroy the surface.
Preferred Procedure
Use the following procedure on most occasions.
Blow away any dust or dirt with compressed air.
1
Procedure for Stubborn Dirt
To clean devices that are extremely sensitive to mechanical
stress or pressure you can also use an optical clean polymer
film. This procedure is time-consuming, but you avoid
scratching or destroying the surface.
Put the film on the surface and wait at least 30 minutes to
1
make sure that the film has had enough time to dry.
Remove the film and any dirt with special adhesive tapes.
2
Alternative Procedure
For these types of optical devices you can often use an
ultrasonic bath with isopropyl alcohol. Only use the ultrasonic
bath if you are sure that it won't cause any damage any part of
the device.
Put the device into the bath for at least three minutes.
1
Blow away any remaining liquid with compressed air.
2
If there are any streaks or drying stains on the surface, repeat
the cleaning procedure.
