2 Clean the interface by rubbing the cotton-swab over the
surface using a small circular movement.
3 Take a new, dry soft-tissue and remove the alcohol,
dissolved sediment and dust, by rubbing gently over the
surface using a small circular movement.
4 Blow away any remaining lint with compressed air.
How to clean optical devices
sensitive to mechanical stress
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.
1 Blow away any dust or dirt with compressed air.
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.
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.
