− First, loosen the clamping screw (Fig. 16/ 12 ) on
the condenser carrier and pull the condenser
out to the front (if necessary, lower the
condenser carrier using the knurled knob
(Fig. 16/ 22 )).
− Unscrew the slotted screw (Fig. 24) and screw it
into the corresponding bore hole to the right or
left of it. Insert the condenser again.
•
Push the slider to the right until perceiving the
lock-in position (to the right or left in the case
of the slider with two phase contrast positions)
to move the phase stop into the light path.
The filter (
∅
22 mm) in the mid-
position of the slider Ph 1 / H / Ph 2
has been factory-installed. After
removing the supporting ring it can be
exchanged or removed.
•
Open the aperture diaphragm of the condenser completely using its control lever (left limit stop).
•
Adjust the illumination intensity as needed.
•
Check the centering of the phase stop according to the drawing in Fig. 23. To this end, remove one
eyepiece and replace it by the diopter.
•
Center the phase stop, if necessary, (Fig. 23/ A ) by turning the two adjusting screws of the slider
(Fig. 22/ 5 ) by means of the two Allen keys SW 1.5 (Fig. 22/ 4 ) until the phase stop image corresponds
to that shown in (Fig. 23/ B ).
•
Afterwards, replace the diopter by the eyepiece again.
For darkfield applications, use the darkfield slider in place of the phase-contrast slider.
