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.
Preferred Procedure
Use the following procedure on most occasions.
1 Blow away any dust or dirt with compressed air.
Procedure for Stubborn Dirt
Use this procedure particularly when there is greasy dirt on the lens:
