Agilent 86038B Photonic Dispersion and Loss Analyzer, Second Edition
Preferred Procedure
Use the following procedure on most occasions.
1 Blow away any dust or dirt with compressed air.
Procedure for Stubborn Dirt
Use this procedure when there is greasy dirt on the lens:
Only use water if you are sure that there is no other way of
cleaning your optical device without causing corrosion or
damage. Do not use hot water, as this may cause mechanical
stress, which can damage your optical device.
Ensure that your liquid soap has no abrasive properties or
perfume in it. You should also avoid normal washing up liquid,
as it can cover your device in an iridescent film after it has been
air dried.
Some lenses and mirrors also have a special coating, which may
be sensitive to mechanical stress, or to fat and liquids. For this
reason we recommend you do not touch them.
If you are not sure how sensitive your device is to cleaning,
please contact the manufacturer or your sales distributor.
1 Moisten the lens or the mirror with water.
2 Put a little liquid soap on the surface and gently spread the
liquid over the whole area.
3 Wash off the emulsion with water, being careful to remove it
all, as any remaining streaks can impair measurement
accuracy.
4 Take a new, dry soft tissue and remove the water, by rubbing
gently over the surface using a small circular movement.
5 Blow away remaining lint with compressed air.
Alternative Procedure A
To clean lenses 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.
