6.14 Inserting the Front Module Slider

If your microscope is prepared for integrated
modulation contrast or integrated phase con-
trast, a front module (possibly in conjunction with
a manual magnifi cation changer) will be integrat-
ed in the stand. This is recognizable by a 2 x 3 cm
opening at the left front side of the microscope.
If this opening is not present or closed, then your
microscope is not prepared for the integrated
processes.
A slider for integrated modulation contrast or in-
tegrated phase contrast fi ts in this opening. The
phase contrast slider may still require the instal-
lation of phase rings.
Insert the slider with the markings facing for-
ward. It features a bright fi eld position and two
positions for contrast methods (position A and
position C).
(A and C designate the eyepoint of the used ob-
jective. Please refer to the included objective list
for the eyepoint of your objective. It can also be
found engraved on the objective.)

6.15 Installation of the Polarizer and Analyzer

Installed at the factory.
To change the components, proceed as follows:
Motorized condenser:
See included installation instructions.
Manual condenser:
Attach the single or triple position holder to the
top of the manual condenser. The holder has a
guide that must be inserted in the opening next
to the screw threads. The holder must be posi-
tioned so that the polarizer or fi lter to be used
covers the opening of the condenser.
Insert the polarizer or fi lter with the correct side
facing up into the holder (λ: lambda and polar-
izer; POL: polarizer only). A click mechanism will
indicate proper seating. The polarizer must turn
easily between the two stops (approx. 30°).
