7. Rotate the prism movement knob of the DIC slider in the clockwise direction
all the way until the knob is stopped. A black interference stripe then a rain-
bow-colored interference stripe will be observed. Here, stop the knob at the
position with which the black interference stripe can be seen. (Fig. 7)
8. While observing the objective’s exit pupil, rotate the polarizer rotation dial
ƒ on the polarizer unit until the black interference stripe becomes darkest.
This is the position for using the polarizer. (Figs. 5 & 7)
}If two black interference stripes are observed, rotate the polarizer by about
90° so that only one black interference stripe is visible.
}The “cross-Nicol” position is located near the 0° position indication.
9. After determining the position, tighten the polarizer-clamping knob … so
that the polarizer will not rotate.
