) into the beam path.
•
Rotate the lever of the lambda/4 plate of the circular polarizer D (Fig. 4-10/
3
) until maximum
extinction is achieved (dark-gray field of view) (lever points 45° to the right).

Components for circular polarization contrast
•
An (anisotropic) specimen should not be examined until after the above adjustment.
•
Reinsert the specimen to be examined.
The interference colors – which depend on the material, specimen thickness and orientation – of the
specimens appear constant and independent of stage rotation.
