croscopy Using the KÖHLER
Method [
.
Wrong thickness of the frame
glass when using a transmitted
light objective with a frame
glass thickness correction of
0.17 mm.
Use standardized frame
glasses with a thickness of
0.17 mm.
Specimen holder is not in-
serted correctly.
Turn the sample holder over,
the sample side shows up.
No immersion oil or an un-
specified 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 sur-
faces of objectives, eyepieces,
condensers or filters.
Clean the soiled optical com-
ponent.
Parfocal performance not
good on Axioscope 7
The focal plane was adjusted
using the low-magnification
objective which has a larger
depth of focus than the high-
magnification objective.
Determine the focal plane us-
ing the high-magnification ob-
jective.
There is a backlash of Z-axis
drive.
Adjust the focal plane from
the same direction for all the
objectives.
No light in eyepiece
The system is in ECO mode.
Turn the Intensity/LM knob
clockwise to wake up the sys-
tem.
The light intensity is too low.
Turn the Intensity/LM knob
clockwise to increase the light.
The light was turned off by an-
other pressing of the respec-
tive RL/TL button.
Press the RL or TL button ac-
cording to the corresponding
indicator in green color.
LED connector is loose (when
using builtin LED10 illumina-
tion).
Unmount the LED10 lamp case
from the microscope stand,
unplug and reinsert the con-
nector to the socket. Check
again.
