9.2.1
Cleaning of the Optical Parts
• Clean all easily accessible optical parts once a
week.
• Carefully wipe the optical parts with a Kleenex
tissue moistened with alcohol of 70 to 80 %.
9.2.2
Cleaning When Actually Dirty
Actual dirt, e. g. caused by finger prints or immer-
sion oil, must immediately be removed, otherwise
the optical functions will permanently be impaired.
Dirt on surfaces of lenses or filters burnt-in by
laser light can not be removed any more.
• Slightly moisten a Kleenex tissue with pure
alcohol (100 %) or spirit and wipe the dirty
parts very carefully.
• Clean dry objectives and oculars smoothly with
a cotton bud or a tooth pick padded with cotton
wool. Only use surgical cotton from the phar-
macy.
• Remove cotton fluffs and similar by blowing
with a small pair of bellows, such as an enema
syringe.
Caution
Before starting any maintenance works, dis-
connect all system components from the
mains.
Caution
Moisten cleaning tissue only slightly, do not
soak. Excessive solvent might dissolve the
cementing of the lenses.
Do not use acetone for cleaning, at any rate.
