6. Assembly
All the Leica DMI 6000 B microscope condens-
ers feature 7-position turrets and can be
equipped individually with suitable ring dia-
phragms for phase contrast (PH), darkfield (DF)
or IC prisms for DL interference contrast (DIC).
Light rings and condenser prisms are generally
already installed in the turret at the factory,
making the following assembly steps unneces-
sary. Please continue on

of Condensers.
To change the components, proceed as follows:
Installing the Light Rings
Change the light rings only with the instrument’s
power turned off. To change the light rings, start
by removing the complete condenser from the
transmitted light illumination axis. Simply re-
lease the socket-head screw at the right side of
the condenser mount. The condenser can now
be removed very easily with Leica’s own con-
denser quick release. Open the condenser cov-
er at the top right side. You will now have access
to the various numbered openings for the light
rings.
Install light rings for phase contrast (designated
by the ID numbers 0, 1, 2, 3 and the focal inter-
cept S of the corresponding condenser head)
and the DF diaphragm (designated by D for dark-
field and the focal intercept S of the correspond-
ing condenser head) in the positions of the turret
disk as follows:
