8. Operation

8.2.4 Polarization (TL)

• Use the 

TL/IL

  function button to switch to

transmitted light (TL).

• Select the 

POL 

(polarization) contrast method

by pressing the variable button 

POL

.

Alternatively: press the variable button

CHANGE TL 

    

.

(For details on button assignments, please see
the identification sheet.)

POL

 will appear on the LeicaScreen.

Manual Method:

• Move the polarizer on the condenser into the

beam path.

• Insert the analyzer into the right side of the

stand until it clicks into position (Fig. 110).

• Bring the polarizer and analyzer into cross

position until they reach maximum darkness.

• Place a specimen on the stage and select a

suitable objective.

Motorized Method:

• If the microscope is equipped with the rel-

evant components, the polarizer will be acti-
vated automatically in the condenser when
the 

POL 

contrast method is selected. The ana-

lyzer cube is also automatically positioned in
the beam path.

Combined Methods:

• The Leica DMI6000 B microscope permits

purely mechanical and motorized components
— such as a mechanical analyzer and motor-
ized polarizer — to be combined.
