5. CLEANING AND CARING FOR THE MICROSCOPE
To keep the microscope in good working order, avoid
dust and water
. If any dust or water happens to
get into the microscope, fungus will grow, damaging the microscope. Please note that once fungus has
grown, even after cleaning, the problem may reoccur.
Grease stains
and
fingerprints
affect image quality; avoid allowing fingers to come into contact with
the surface of optical components.
5.1 Protection against Dust
If the instrument is not to be used for a long period of time, cover it with the dust cover provided. Never
leave the eyepiece tube exposed. Either leave the eyepiece in the tube (recommended if the
microscope is frequently used) or cover it with wrapping paper or a covering cap. Eyepieces and other
optical components that will not be used for a relatively long period of time should be stored in a dry
cardboard box, preferably with a desiccating agent added, to shield against dust and moisture.
5.2 Protection against Water and Moisture
The instrument should be kept away from all water sources, including pipes and sinks. Humidity in the
room where the instrument located should be kept as low as possible (relative humidity should be kept
below 70%). It is recommended that optical components be kept in a dry box when not in use,
preferably with a desiccating agent added. The use of dehumidifier and/or 24-hour air conditioning is
highly recommended if the surrounding area is humid.
5.3 Cleaning
5.3.1
If dust is found on the optical surface, remove by using an air blower or compressed air.
5.3.2
For fingerprint, grease stains or dust which cannot be removed using air, two possible methods
are
recommended:
●
Breathe lightly on the glass surface and wipe with a clean piece of cloth, lens paper or cotton swab.
Please note that small cotton fibers may remain on the surface of the lens if a cotton swab is used.
●
Use a cotton swab or lens paper dipped in a small amount of pure alcohol and clean the lens surface
carefully. No other aggressive solvents should be used.
