Adjusting transmitted-light phase
contrast or transmitted-light
darkfield
•
First, adjust the microscope as you do for
brightfield.
•
Turn the nosepiece to swing the phase-contrast
objective (40x/Ph 2) into the light path.
•
Open the luminous-field diaphragm (Fig. 9/
3
, if
adjustable) on the stand and open the aperture
diaphragm by means of control lever (Fig. 9/
1
)
on Abbe condenser (Fig. 9/
2
).
•
If the phase-contrast slider (Fig. 9/
6
) was not
factory-installed yet, first unscrew its screw
(Fig. 9/
7
). Then, push the slider from the left
into the Abbe condenser and screw the screw
(Fig. 9/
7
) back in again.
•
Push the slider to the right as far as it will go to
move the phase stop into the light path.
•
Move the control lever of the aperture
diaphragm to fully open it on the Full Köhler
model or set it to the
PH
mark on the Fixed
Köhler model.
•
Adjust the illumination intensity as needed.
•
Check the centering of the phase stop
according to the drawing in Fig. 10. To this end,
remove one eyepiece and replace it by the
eyepiece telescope.
•
Center the phase stop, if necessary, (Fig. 10/
A
)
by turning the two adjusting screws of the
slider (Fig. 9/
5
) by means of the two Allen keys
SW 1.5 (Fig. 9/
4
) until the phase stop image
corresponds to that shown in Fig. 10/
B
.
•
Afterwards, replace the eyepiece telescope by
the eyepiece again.
For darkfield applications, use the darkfield slider in place of the phase-contrast slider.
