3
Blow away any remaining lint with compressed air.
Procedure for Stubborn Dirt
Use this procedure when there is greasy dirt on the interface, and
using the preferred procedure is not sufficient. Using isopropyl
alcohol should be your last choice for recessed lens interfaces because
of the difficulty of cleaning out any dirt that is washed to the edge of
the interface:
1
Moisten a new cotton swab with isopropyl alcohol.
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 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.
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.
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.
1
Put the device into the bath for at least three minutes.
2
Blow away any remaining liquid with compressed air.
