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 when there is greasy dirt on the lens:
C A U T I O N Only use water if you are sure that there is no other way of cleaning
your optical device without causing corrosion or damage.
Only use water if you are sure that there is no other way of cleaning
your optical device without causing corrosion or damage. Do not use
hot water, as this may cause mechanical stress, which can damage
your optical device.
Ensure that your liquid soap has no abrasive properties or perfume in
it. You should also avoid normal washing up liquid, as it can cover
your device in an iridescent film after it has been air dried.
Some lenses and mirrors also have a special coating, which may be
sensitive to mechanical stress, or to fat and liquids. For this reason we
recommend you do not touch them.
