7.4 Adjustment of Condenser Prisms
In case of complete delivery, the condenser
prisms will already have been adjusted at the
factory, but it is advisable to check the adjust-
ment from time to time, especially after transport.
• Pull out the objective prism slide (34.1) partly or
fully.
• Swivel in a suitable objective and focus on the
specimen.
• Swing in the condenser head.
The condenser head is swung out for objective
magnifi cations < 10x.
• Set the Köhler illumination (

• Insert the centering screws into the openings
provided at the rear of the condenser (33.1).
• Turn the centering screws until the dark ring
(phase ring in the objective) is congruent with
the slightly narrower bright ring (light ring in
condenser) (32 c).
• Repeat the process for all other light rings.
• Remove the centering keys after the centering
procedure.
