Setting the DIC Slider

1. Loosen the mounting knob @ on the front of the DIC revolving nose-

piece, insert the DIC slider ² so that the surface with indication faces up,

and clamp by tightening the mounting knob.

2. With the U-DICR interference slider, set the slide lever ³ according to the

objective in use.

3. With the U-DICRH or U-DICRHC slider that does not have the slide lever,

the applicable objectives are as follows.

Observation Method

1. Place the specimen on the stage and adjust the focus by moving the

stage up or down.

2. Adjust the field iris diaphragm so that its image circumscribes the field of

view.

3. The contrast may sometimes be enhanced by closing the aperture iris

diaphragm slightly.

1. Adjust the background contrast by turning the prism movement knob |

on the DIC slider as described below. (Fig. 31)

2. When the prism movement knob on the DIC slider is turned, the interfer-

ence color in the background varies continuously from the gray sensitive

color to magenta sensitive color (from -100 to 600 nm). Set the interfer-

ence color which can provide best contrast with respect to the specimen.

· Selecting a gray background color enables 3D-looking observation with

high contrast thanks to the highest sensibility of the gray sensitive color.

· Selecting a magenta sensitive color allows even small phase variation to

be observed as a change in color.
