Cleaning Information 4
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.
Preferred Procedure
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.
Procedure for Stubborn Dirt
Use this procedure particularly when there is greasy dirt on the lens:
1 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.
