Care and Maintenance

7.1

Lens Cleaning

Do not let dust, fingerprint, etc. get on the lenses. Dirt on the lenses, filters, etc. will adversely
affect the view of image. If any of the lenses get dirty, clean them as described below.
Either brush away dust with a soft brush, or else gently wipe it off with a piece of gauze.
•
Only if there are fingerprints or grease on a lens, dampen lightly a piece of soft, clean
•
cotton cloth, lens tissue, or gauze with absolute alcohol (ethyl or methyl) and gently wipe
off the dirt.
When removing the immersion oil off from the objective, use only petroleum benzine. For
•
optimum results, we recommend following up petroleum benzine with absolute alcohol
(ethyl or methyl alcohol). If petroleum benzine is unavailable, use methyl alcohol alone.
However, methyl alcohol does not clean as well as petroleum benzine, it will be necessary
to wipe the surface repeatedly. (Usually, three or four times are sufficient to clean the
lenses.)
Never use petroleum benzine to clean the entrance lens of the eyepiece tube or prism
•
surface of the eyepiece tube.
• Absolute alcohol and petroleum benzine are highly flammable. Be careful when handling
it, when around open flames, when turning the power switch on/off, etc.
• When using petroleum benzine or absolute alcohol, always follow the instructions
provided by the manufacturer.
