Rotate the prism movement knob
d
of the DIC slider
b
within the
range from -100 to 600 nm to adjust the background color contrast.
Rotating the prism movement knob
d
on the DIC slider
b
varies the
background interference color continuously from gray sensitive color
to magenta sensitive color (–100 to 600 nm). Set the interference color
providing highest contrast for the specimen in use.
} When the background color is set to the gray color, observation with
excellent contrast and three-dimensionality can be performed due
to the highest-speed gray sensitive color.
} When the background color is set to the magenta sensitive color,
even very small change in phase can be observed as change in
color.
} When using the autofocus unit STM7-AF, the focusing may not be
available within the adjustment range (where the interference color
is near orange.) of certain DIC prisms.
