Alternative procedure
For these types of optical devices you can
often use an ultrasonic bath with isopropyl alcohol. Only use the
ultrasonic bath if you are sure that it won’t cause any damage to
any part of the device.
1 Put the device into the bath for at least three minutes.
2 Blow away any remaining liquid with compressed air.
If there are any streaks or drying stains on the surface, repeat
the cleaning procedure.
How to clean bare fiber ends
Bare fiber ends are often used for splices or, together with other
optical components, to create a parallel beam.
The end of a fiber can often be scratched. You make a new
cleave. To do this:
1 Strip off the cladding.
2 Take a new soft tissue and moisten it with isopropyl alcohol.
3 Carefully clean the bare fiber with this tissue.
4 Make your cleave and immediately insert the fiber into your
bare fiber adapter in order to protect the surface from dirt.
