interference color in the background varies from -100 to 100 nm. Set the

retardation which can provide best contrast.

· 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.

To select the magenta sensitive color as the background color, use the U-

POTP3 polarizer and insert it so that the

# Since the DIC observation has a high detection sensitivity, take care

against contamination on the specimen surface.

}The detection sensitivity is variable depending on direction so it is recom-

mended to use a rotary stage.
