VII. Care and Maintenance
1
Cleaning Lenses and Filters
Do not let dust, fingerprints, etc., get on lenses and filers. Dirt on lenses, filters, etc., will adversely
affect the view of the image. If any lens gets dirty, clean it as described below.
•
Either brush away dust with a soft brush, or wipe it away gently with gauze.
•
Only in cases of fingerprints or grease, dampen a piece of soft, clean cotton cloth, lens tissue, or
gauze with absolute alcohol (ethyl or methyl alcohol) and wipe. (Use a piece of cleanroom wiper
in the cleanroom instead of cotton cloth, lens tissue, and gauze.)
•
Absolute alcohol requires care in handling as it is highly flammable. Be careful when using fire
or turning on/off the power switch nearby.
•
Follow the instructions provided by the manufacturer when using absolute alcohol.
2
Cleaning the Painted, Plastic, and Printed Parts
Do not use organic solvents (alcohol, ether, and paint thinner, etc.) on painted, plastic, or printed
parts. Doing so could result in discoloration or in the peeling of printed characters. If the dirt is hard
to remove, wipe it gently using a piece of gauze dampened with a neutral detergent solvent. (Use a
piece of cleanroom wiper in the cleanroom instead of gauze.)

Storage
•
Store the microscope in a dry place where mold is not likely to form.
•
Store the objectives and eyepieces with a drying agent in a desiccator or similar container.
•
Put a plastic cover over the microscope to protect it from dust.
•
Before putting on the plastic cover, turn off the power switch of the microscope (flip it to the “ ”
side) and wait until the lamphouse is cool.
