How to clean lenses

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 alcohol 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 Clean the lens by rubbing a new, dry cotton-swab over the surface
using a small circular movement.
2 Blow away any remaining lint with compressed air.
Use this procedure particularly when there is greasy dirt on the lens:
1 Moisten a new cotton-swab with isopropyl alcohol.
2 Clean the lens by rubbing the cotton-swab over the surface using a
small circular movement.
3 Using a new, dry cotton-swab remove the alcohol, any dissolved
sediment and dust.
4 Blow away any remaining lint with compressed air.
How to clean instruments with a
fixed connector interface
N O TE Both the surface and the jacket of the attached connector should be
completely dry and clean.
You should only clean instruments with a fixed connector interface
when it is absolutely necessary. This is because it is difficult to remove
any used alcohol or filaments from the input of the optical block.
It is important, therefore, to keep dust caps on the equipment at all
times, except when your optical device is in use.
