Placing the polarizer into the optical path
• Attaching the polarizer: Remove the vertically
oriented cover at the right side of the illuminator. And
then, insert the polarizer slider into the rear slot with
its orientation indication facing toward the eyepieces.
Insert the dummy slider or the lambda plate slider into
the front slot. (See Page 83.)
• Placing the element into the optical path:
When the polarizer slider is pushed into the first click-
stop position, the empty hole is placed into the optical
path. And when the polarizer slider is pushed into the
second click-stop position, the polarizer is placed into
the optical path. The orientation of the polarizer can
be set by turning the polarizer rotation ring.
Removing the polarizer from the optical path
When the polarizer is placed in the optical path and you wish to remove the polarizer from the
optical path, pull the polarizer slider toward the right to the first click-stop position. (The empty
hole will be placed into the optical path.)
Orientation adjustment for the polarizer
The orientation of the polarizer can be changed by
turning the polarizer rotation ring. Perform
tgÀêfollowing to make a crossed Nicols position with
the polarizer and the analyzer.
Place the polarizer and the analyzer in the optical path.
And then, place a specimen with a flat and plain
surface onto the stage. Set up the microscope for the
simplified polarization microscopy under the epi
illumination.
Remove one eyepiece from the eyepiece tube and look
inside the open sleeve. You can see the pupil of the
objective as a bright circle.
Turn the polarizer rotation ring in either direction until
a dark cross appears in the viewfield as shown in the
figure. This is the crossed Nicols position. (Matching
the marks on the polarizer rotation ring as shown in
on the illustration will bring about the crossed Nicols
position as well.)
