Maintenance and Cleaning
Always place the dustcover over the microscope after use. Keep the eyepiece
and objectives always mounted on the microscope to avoid dust entering the
instrument.
Cleaning the optics
When the eyepiece lens or front lens of the 10x or S40x objective are dirty
they can be cleaned by wiping a piece of lens paper over the surface (circular
movements). When this does not help put a drop of xylol or alcohol on the lens
paper. Never put xylol or alcohol directly on the lens!
When dirt is clearly visible in the field of view it resides on the lowest lens of the
eyepiece. By using the Allen-key the eyepiece can be removed from the tube.
Clean the outside of the lens.
In case there is still dust visible please check if the dust is in the eyepiece by
turning it. If this is the case remove the lowest lens carefully from the eyepiece
and clean it.
It is not necessary – and not recommended – to clean the lens surfaces at the
inner side of the objectives. Sometimes dust can be removed with high pressured
air. There will never be dust in the objectives if the objectives are not removed
from the revolving nosepiece.
Caution
•
Cleaning cloths containing plastic fibers can damage the coating of the
lenses!
