}An analyzer and polarizer are required for simplified polarized light observation. The applicable condenser is the IX2-
LWUCD or IX2-LWUCDA2. When the IX-ULWCD is used, the simplified polarized light observation is not available.
1 Attaching the Analyzer and Polarizer
}Use the same procedure as that for attaching the analyzer and polarizer
for DIC observation (see pages 40-41).
2 Observation Method (Fig. 67)
1. Rotate the turret to select the “BF” brightfield observation (with no optical
element engaged in the light path).
2. Slide the polarizer detaching lever @ on the IX-LWPO polarizer unit to
engage the polarizer in the light path. (Fig. 67)
3. Attach the objective to be used to the revolving nosepiece and rotate it to
engage the objective in the light path.
4. Slide the polarizer rotation/clamping knob ² on the polarizer unit
horizontally in the counterclockwise direction around the axis until
the position with which the field of view is darkest. (Fig. 67)
5. Clamp the polarizer rotation/clamping knob so that the polarizer will not
rotate.
6. Place a specimen on the stage and bring the specimen into focus.
Now the specimen can be observed with simplified polarized light
observation.
7. Adjust the field iris diaphragm so that its image circumscribes the field of
view.
8. Adjust the aperture iris diaphragm to enhance the contrast.
}Refer to the separate instruction manual.
