MICROSCOPE MAINTENANCE
General
Routine optical and mechanical maintenance of compound microscopes can ensure that
your microscope works well for years.
Most microscope problems occur as a result of improper handling. When carrying the
microscope, always hold it by the base and the metal support arm. Do not pick it up by
grabbing the stage, as this can cause mis-alignment for the mechanical stage. If you will
be transporting the microscope frequently from one location to another you might consider
purchasing a microscope carrying case.
When the microscope is not in use keep it covered with the dust cover. This alone will
extend the life of your microscope. Even if the microscope is stored within a cabinet, you
should still cover it with the dust cover. Do not store a microscope without any eyepieces,
even if it is covered. This can allow dust to collect within the eye tubes, which can be
difficult to clean. If the microscope eyepieces must be removed, simply cover the tubes
with caps or a plastic bag with a rubber band around the eye tube.
If you are using immersion oil the high power objective lens (usually 100x) and the lens of
the condenser should be thoroughly cleaned before storing. After using the microscope,
turn off the illuminator and wait for it to cool for several minutes before putting it away. By
allowing the bulb to cool you will extend its life. Also, make sure you do not store your
microscope in an area that has corrosive chemical fumes that can destroy lenses or metal
parts.
Never attempt to disassemble any part of the microscope for repair unless you are a
experience user. If not and there is any problem with the microscope, contact the
microscope reseller in your area or a qualified technician.
Treat the microscope with care! Never expose it to sharp knocks, vibrations, moisture,
dust, or direct sunlight for long periods of time.
Humidity causes fungal growth on the surfaces of lenses and prisms. This can cause
cloudiness of the view field and rusting of metal parts of the microscope. To protect from
fungus, always keep the glass surface as clean as possible and free of dirt and
fingerprints. In very humid areas, keeping the microscope inside a temperature controlled
cabinet, and using silica gel (desiccant) or anti-mold strips may be useful.
