Setting The Motorized Polarizer; Adjusting The Light Sources - Leica Microsystems DMI3000 B Mode D'emploi

7.9 Setting the Motorized Polarizer

Remove your specimen from the stage.
Leica DMI3000 B:
• Set the condenser to the bright fi eld position.
• Insert the analyzer into the analyzer slot on
right side of the stand.
• Activate the polarizer.
• Turn the polarizer until you have the optimal
dark position.
Leica DMI4000 B and Leica DMI6000 B:
For manual condensers, proceed as described
above for the DMI3000 B.
• Select the POL method (one of the variable
function buttons on the stand). If the analyzer
is present on the Fluo turret as an analyzer
block, it will move into position automatically. A
manual analyzer must be positioned by hand.
In the case of motorized condensers with mo-
torized polarizers, the polarizer will move into
position automatically.
• Insert the centering key in the opening provid-
ed on the condenser (Fig. 96).
• Set up optimal darkening. (The analyzer must
be in place.)
• Remove the centering keys.
Replace your specimen on the stage.
