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.
