How to clean optical devices which are
sensitive to mechanical stress and pressure
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.
Use the following procedure on most occasions.
1 Blow away any dust or dirt with compressed air.
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.
1 Put the film on the surface and wait at least 30 minutes to make
sure that the film has had enough time to dry.
2 Remove the film and any dirt with special adhesive tapes.
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 anything to the device.
1 Put the device into the bath for at least three minutes.
2 Blow away any remaining liquid with compressed air.
If there are any streaks or drying stains on the surface, repeat the
cleaning procedure.
