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 9µm. 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 swabover 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 inter-face.

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.
