Never look into an optical output, because this can seriously damage
your eyesight.
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 project onto the card and
becomes visible as a small circular spot.
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.
Use this procedure particularly 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.
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 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.
