1. Adjust the polarizer in accordance with the following procedure.
@Engage the transmitted light DIC prism slider in the light path and tighten the clamping knob. Then
engage the reflected light analyzer (U-ANT or U-AN) in the light path.
²Rotate the turret to select the BF brightfield observation light path (with no optical element engaged).
³Push in the polarizer handling knob to insert the polarizer into the light path.
Operation using U-DICT and U-ANT
a) Rotate the prism control knob of the transmitted light DIC prism slider clockwise as far as it will go.
b) Rotate the revolving nosepiece to swing in the 10X objective, bring the specimen into approximate focus,
and remove the eyepiece. You can see the pupil of the objective if you look into the inside of the eyepiece
sleeve. (You can see the pupil more easily if you use the U-CT30 centering telescope.)

c) As you rotate the polarizer rotation knob while looking at the
objective pupil, a black fringe may appear at a certain posi-
tion. The polarizer should be rotated to the position where a
single fringe appears darkest. (Fig. 3)
#If two black fringes appear, rotate the polarizer by approxi-
mately 90
o
so that only one black fringe is visible.
d) Once the position of the polarizer is determined, tighten the
clamping knob to clamp the polarizer.
e) Replace the eyepiece to the original position.
