of the DIC slider to select the
interference color with the highest contrast suitable for the sample.
U-DICR, U-DICRHC
The interference color of the background changes continuously
from the gray sensitive color to the magenta sensitive color (from
-100 to 600 nm).
U-DICRH
The interference color of the background changes continuously
from -100 to 100 nm.
· If you select the gray color for the background color, you can
observe the three dimensional image with high contrast in the
gray sensitive color with the highest sensitivity.
· If you select the magenta sensitive color for the background color,
even a small phase difference can be viewed as a variation of the
color.
The detection sensitivity during DIC observation is very
high. Be careful, particularly, for dirt or dust on the sample
surface.
· As the detection sensitivity is directional, it is recommended to
use a rotary wafer holder together or rotate the sample during
observation.
· Narrowing down the aperture diaphragm appropriately may
increase the contrast.
