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 particularly when there is greasy dirt on the lens:
1 Moisten the lens or the mirror with water.
2 Put a little liquid soap on the surface and gently spread the liquid over the
whole area.
3 Wash off the emulsion with water, being careful to remove it all, as any
remaining streaks can impair measurement accuracy.
4 Take a new, dry soft-tissue and remove the water, by rubbing gently over the
surface using a small circular movement.
5 Blow away remaining lint with compressed air.
Alternative Procedure A
To clean lenses that are extremely sensitive to mechanical stress or pressure you
can also use an optical clean polymer film. This procedure is time-consuming, but
you avoid scratching or destroying the surface.
1 Put the film on the surface and wait at least 30 minutes to make sure that the
film has had enough time to dry.
2 Remove the film and any dirt with special adhesive tapes.
Alternative Procedure B
If your lens is sensitive to water then:
1 Moisten the lens or the mirror with isopropyl alcohol.
2 Take a new, dry soft-tissue and remove the alcohol, dissolved sediment and
dust, by rubbing gently over the surface using a small circular movement.
3 Blow away remaining lint with compressed air.
Only use water if you are sure that your device does not corrode.
Do not use hot water as this can lead to mechanical stress, which
can damage your device.
Make sure that your liquid soap has no abrasive properties or
perfume in it, because they can scratch and damage your device.
Do not use normal washing-up liquid as sometimes an iridescent
film remains.
