2. When the slider movement knob on the U-DICRH DIC slider is turned, the
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
the front.
# 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.
