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.
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.
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.
To clean devices that are extremely sensitive to mechanical stress or
pressure you can also use an optical clean polymer film. This
