Cleaning Lenses
Keeping your unit’s lenses clean and free of dust will ensure that you get
the optimum performance out of your unit. The following
recommendations will help you with the cleaning process:

With a filtered air blower or a soft bristled brush, remove as much dust
and dirt as possible.

Apply a few drops of cleaning solution, which is used to clean camera
lenses, on a lens tissue, a cleaning cloth or a lint-free swab. The lens
cleaning solution especially manufactured by camera lens
manufacturers can be used safely. Reagent grade isopropyl alcohol as
well as deionized water can also be used safely.

Gently remove oil, fingerprints and grime from the lens surface, using a
circular motion from the center outwards.

EXFO recommends to clean the lenses only when necessary,
beginning with the parts that are the most exposed to dust and
dirt. For example, the lens that is located at the end of the optical
head (just behind the SmarTip) can need cleaning, but not the other
lenses.
Attempting to clean lenses that do not need cleaning, especially
without the right tools or method, can worsen a situation.
