MIC-200 Series / 1720
Focus the image with the S40x lens.
Rotate the revolving nosepiece until the S100x objective
almost (not quite) clicks into place.
Drop a small drop of immersion oil (not part of the scope
of delivery, please order separately) on the center of the
specimen.
Then let the S100x objective snap into place.
The front lens is now in contact with the immersion oil.
View the specimen through the eyepiece and focus the
image with the fine adjustment knob.
The distance between objective lens and specimen is on-
ly 0.24mm!
If small bubbles are visible, turn the S100x objective a
few times to the left and right so that the front lens of the
objective moves in the oil. This will make the bubbles
disappear.
Then turn the stage with the fine adjustment knob down-
wards until the front lens does not touch the oil anymore.
Always clean the front lens of the S100x lens with a piece
of lens paper moistened with a drop of xylene or alcohol.
Now also clean the micro slide.
The S100x objective can also be used without immersion oil,
i.e. dry. However, please note that in this case the resolution
is much lower. Water may provide somewhat better resolu-
tion than using it dry.
Caution!
Never drop the xylene or alcohol directly onto the ob-
jective lens. This could cause xylene or alcohol to en-
ter the lens and dissolve the lens fixation!
Avoid oil contact with the other lenses!
6 MAINTENANCE AND CLEANING
Always cover the microscope with a dust cover after use. Al-
ways leave the eyepieces and objective lenses mounted so
that no dust can enter the inside parts of the microscope.
Cleaning the optical components
If the eyepiece lenses or the front lenses of the objectives are
dirty, you can clean them by wiping a piece of lens paper
over the lens surface in circular motions. If this does not help,
use a drop of xylene or alcohol on the lens paper. Never put
xylene or alcohol directly on the lens!
If dirt is clearly visible in the field of view, it is on the lowest
lens of the eyepiece. Remove the eyepiece from the tube and
clean the outside of the lens.
If dust is still visible, check whether the dust is in the eye-
piece by rotating it. If so, gently remove the bottom lens from
the eyepiece and clean it.
It is not necessary - and not recommended - to clean the lens
surfaces inside the objectives. Sometimes the dust can be
removed by high-pressure treatment with air. Otherwise,
there will be no dust inside the objectives until the objectives
are removed from the revolving nosepiece.
The most important step to a long lasting clean microscope
optics is to use the dust cover when you are not using your
microscope!
Caution! Cleaning cloths containing plastic fibers can
damage the coating of the lenses!
Maintenance of the stand and mechanical components
Simply remove dust with a brush. If the stand is very dirty, the
surface can be treated with a careful cleaning agent.
All moving parts such as the adjustment of the mechanical or
the coarse and fine focusing mechanism contain ball bear-
ings which are not sensitive to dust. The bearings can be
relubricated with sewing machine oil if necessary.
Change the lamp and the fuse
Switch off the power and pull the mains plug.
Now loosen the lower cover screw of the chassis and re-
move the cover to replace the bulb and fuse according to
the requirements of the different models.
After replacing the bulb and fuse, the cover should be re-
placed and the screws tightened.
