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.

How to clean large area lenses and mirrors

Some mirrors, as those from a monochromator, are very soft and
sensitive. Therefore, never touch them and do not use cleaning tools
such as compressed air or polymer film.
Some lenses have special coatings that are sensitive to solvents,
grease, liquid and mechanical abrasion. Take extra care when cleaning
lenses with these coatings.
Lens assemblies consisting of several lenses are not normally sealed.
Therefore, use as little liquid as possible, as it can get between the
lenses and in doing so can change the properties of projection.
Use the following procedure on most occasions.
1 Blow away any dust or dirt with compressed air.
Use this procedure particularly when there is greasy dirt on the lens:
Only use water if you are sure that your device does not corrode.
Do not use hot water as this can lead to mechanical stress, which
can damage your device.
Make sure that your liquid soap has no abrasive properties or
perfume in it, because they can scratch and damage your device.
Do not use normal washing-up liquid as sometimes an iridescent
film remains.
1 Moisten the lens or the mirror with water.
2 Put a little liquid soap on the surface and gently spread the liquid
over the whole area.
3 Wash off the emulsion with water, being careful to remove it all, as
any remaining streaks can impair measurement accuracy.
