Caution
 Never put a drop of xylol or alcohol directly on the lens of the objective. It could enter the
objective and dissolve the glue that holds the lenses!
 Avoid oil contact with any of the other objectives!

7.0 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.

7.1 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 fibres can damage the coating of the lenses!
