includes two parallel-aligned polarization fil-
ters, which can be pushed to the left side in
the path of the light beam with the help of one
of the two knobs. The microscope must not be
refocused when observing with or without a
polarization filter. It is possible to insert com-
pensators for the determination of path differ-
ences on double-refracting materials or of rota-
tions of the polarization level. According to in-
tended use, a tipping or rotating compensator
inside the two guides on the right side of the
filter pusher can be inserted diagonally to one
of the polarizers.

the turntable so that the markings on it agree
with those on the turntable. When using it in
combination with the filter pusher, align it to
the darkening while looking through the bin-
ocular tube and fasten it with both screws.
