Problem Cause Troubleshooting
Low resolving power and poor
image contrast.
Immersion oil on the front lens of
a dry objective.
Clean the front lens of the dry
objective; see p. 196.
The cover-slip correction ring has
not been set to the correct cover-
slip thickness.
Set the correction ring to the
correct thickness; see p. 27.
Dirt or dust on the optical surfaces
of objectives, eyepieces,
condensers or filters.
Clean the respective optical
components; see p. 196.
Asymmetrically blurred images,
e.g. one side in focus, one side
not.
The condenser has not been set
correctly.
Set the condenser correctly;
see p. 162 ff.
The nosepiece has not clicked into
place.
Turn nosepiece until it clicks into
place (click-stop).
The specimen has not been
clamped in position on the stage.
Correctly insert the specimen in
the specimen holder and clamp it.
Major focus differences after
objective change.
The focusing eyepieces have not
been set correctly.
Set the focusing eyepieces to the
appropriate ametropia; see p. 37.
The objective has not been
screwed in completely.
Screw the objective in as far as it
will go.
The tube lens has either not been
inserted or has been inserted but is
superfluous.
Insert the tube lens or remove the
superfluous tube lens.
Left and right fields of view
cannot be combined to create
one image.
The interpupillary distance of the
binocular tube has not been set
correctly.
Set the interpupillary distance
correctly; see p. 38.
The focusing eyepieces have not
been set correctly.
Set the focusing eyepieces to the
appropriate ametropia; see p. 37.
Eye-fatiguing microscopy. The interpupillary distance of the
binocular tube has not been set
correctly.
Set the interpupillary distance
correctly; see p. 38.
The focusing eyepieces have not
been set correctly.
Set the focusing eyepieces to the
appropriate ametropia; see p. 37.
The image brightness is not
acceptable.
Adjust the lamp voltage or insert
the conversion filter.
Binocular tube optically /
mechanically out of alignment.
Have it checked / repaired by
Microscopy Service.
