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 is dirty it 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.
Caution
•
Cleaning cloths containing plastic fibers can damage the coating of the
lenses!
