How to clean instruments with
a recessed lens interface
WA R N I N G
For instruments with a deeply recessed lens interface (for example the Agilent
81633A and 81634A Power Sensors) do NOT follow ths 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.
Preferred Procedure
Use the following procedure on most occasions.
1
Blow away any dust or dirt with compressed air. If this is not sufficient, then
2
Clean the interface by rubbing a new, dry cotton-swab over the surface using a
small circular movement.
3
Blow away any remaining lint with compressed air.
Procedure for Stubborn Dirt
Use this procedure particularly when there is greasy dirt on the interface, and
using the procedure for light dirt 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.

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
