How to clean instruments with a recessed lens
interface
For instruments with a deeply recessed lens interface (for example the Agilent 81633A and
81634A Power Sensors) do NOT follow this procedure. Alcohol and compressed air could
damage your lens even further.
Keep your dust and shutter caps on when your instrument is not in use. This should prevent
it from getting too dirty.
If you must clean such instruments, please refer the instrument to the skilled personnel of
Agilent's service team.
Use the following procedure on most occasions.
1 Blow away any dust or dirt with compressed air.
If this is not sufficient, then
a Clean the interface by rubbing a new, dry cotton swab over the surface using a small
circular movement.
b Blow away any remaining lint with compressed air.
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.
Use the following procedure on most occasions.
1 Blow away any dust or dirt with compressed air.
