1/42
&
tint
plate.
The
quartz
wedge
is
engraved
with
a
scale
and
can
be
used
for
rough
measurement
of
retardation
in
the
range
of
12-62.
It
is
normal
to
bring
the
top
lens
of
the
condenser
into
the
optical
path
when
observing
at
a
magnification
of
10x
or
greater.

1
Determination
of
Extinction
Position
Rotate
the
stage
with
the
specimen
under
the
crossed
Nicols
to
find
the
direction
where
part
of
the
specimen
to
be
