CLEANING THE OPTICAL SYSTEM
Although cleaning the objectives and eyepieces is relatively easy, here are some procedures and simple
techniques to protect the lens coating and assure optimal performance.
Required tools:
e Lens Tissue ® Cotton swabs (Q-tips) © Blower © Magnifier © Cleaning Solution: 7 parts of ether and
3 parts of ethyl alcohol. The mixture ratio depends on room temperature and humidity. When the humidity
is high, the ratio can be changed to 8 parts of ether and 2 parts of ethyl alcohol.
Caution:
Lightly brush the lens surfaces or blow with the blower before wiping with tissue. This removes particles that
may scratch the lens surface.
HOW TO CLEAN OBJECTIVE LENSES
Wet the tip of a cotton swab
with a generous amount of lens
cleaning solution.

HOW TO CLEAN
THE EYEPIECES
Wrap a sheet of lens tissue around
a cotton swab as illustrated. If the

lens tissue looser and thicker. Other-
wise, make a thin, tight wrap.

solution, and wipe the eyepieces from the center
