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.
Preferred Procedure
There is an easy method for removing dust from bare fiber
ends
Touch the bare fiber end with Tesa
® - Tape. All dust will be
removed.
How to clean large area lenses and mirrors
Some mirrors, such 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 sol-
vents, 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.
