How to clean instruments with a physical
contact interface
Remove any connector interfaces from the optical output of the instrument
before you begin the cleaning procedure.
Cleaning interfaces is difficult as the core diameter of a single-mode fiber
is only about 9
µm. This generally means you cannot see streaks or
scratches on the surface. To be certain of the degree of pollution on the
surface of your interface and to check whether it has been removed after
cleaning, you need a microscope.
To assess the projection of the emitted light beam you can use an infrared
sensor card. Hold the card approximately 5 cm from the interface. The
invisible emitted light is projected onto the card and becomes visible as a
small circular spot.
Preferred Procedure
Use the following procedure on most occasions.
1 Clean the interface by rubbing a new, dry cotton swab over the surface
using a small circular movement.
2 Blow away any remaining lint with compressed air.
Procedure for Stubborn Dirt
Use this procedure when there is greasy dirt on 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.
Never look into an optical output, because this can seriously
damage your eyesight.
