5.3.1

Microscope

Problem

Cause

Solution

Shading or brightness irregularities

in the field of view of the
microscope; the field of view is not
fully visible.

The vis/phot push-pull rod/shift knob

on the photo tube is not in correct
functional position (in-between
position).

Move the vis/phot push-pull rod/shift

knob to the correct functional position
(end position).

Nosepiece with objective is not fully
engaged in its locking position.

Engage the nosepiece with the
objective in its locking position.

Condenser is not adjusted correctly.

Adjust the condenser correctly

(adjustment, centering),
see p. 87 ff.

Aperture diaphragm is not adjusted
correctly.

Adjust the aperture diaphragm
correctly (centering, opening),
see p. 87 ff.

Field diaphragm is not adjusted

correctly.

Adjust the field diaphragm correctly

(centering, opening),
see p. 87 ff.

Filter is not correctly inserted in its
slot.

Insert the filter correctly.

Low resolution and poor contrast. Opening of the aperture diaphragm is

not adjusted correctly.

Adjust the opening of the aperture
diaphragm according to the 2/3-rule

and the texture of the sample you are
using,
see p. 87 ff.

Condenser is not focused correctly
and front lens is not connected

correctly.

Focus the condenser and turn the
front lens correctly on or off,

see p. 87 ff.

Wrong thickness of the frame glass
when using a transmitted light
objective with a frame glass thickness
of 0.17 mm.

Use standardized frame glasses with a
thickness of 0.17 mm.

Specimen holder is not inserted

correctly.

Turn the specimen holder over, the

sample side shows up.

No immersion oil or an unspecified
immersion oil is used with immersion
objectives.

Use immersion oil 518 N or 518 F by
ZEISS

Air bubbles in the immersion oil.

Repeat the oiling procedure with fresh
oil.

Immersion oil on the front lens of a

dry objective.

Clean the lens

Correction setting is not set to the
proper thickness of the frame glass.

Adjust the correction setting to the
correct thickness of the frame glass

Dirt or dust on the optical surfaces of
objectives, eyepieces, condensers or
filters.

Clean the soiled optical component
