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.
