Care and Maintenance

Lens Cleaning

7.1
Keep the lens free of dust, fingerprints, etc. Dirt on the lenses or filters will affect image quality.
If any of the lenses become dirty, clean them by the procedure given below.
• Brush away dust with a soft brush or wipe away gently with gauze.
• If fingerprints or grease gets on a lens, moisten a piece of soft, clean cotton cloth, lens
tissue, or gauze with absolute alcohol (ethyl or methyl alcohol) and wipe.
• Use petroleum benzine only to remove immersion oil from the objective. 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. When
using just methyl alcohol, note that surfaces will need to be wiped repeatedly to ensure
complete removal of immersion oil. Usually, three or four times should be sufficient to
clean the lens.
• Never use petroleum benzine to clean the entrance lens at the bottom of the eyepiece
tube or prism surface of the eyepiece tube.
• Absolute alcohol and petroleum benzine are highly flammable. Be careful when handling
these materials, particularly around open flames or when turning the power switch on or
off.
• Follow the instructions provided by the manufacturer when using absolute alcohol.
