Rotate the prism movement knob a of the DIC slider to select the
interference color with the highest contrast according to 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.
*
If you want to select the magenta sensitive color for the
background color, use the polarizer
GX-POTP
and insert it into
the polarizer insertion slot so that mark is visible from the
front.
The detection sensitivity during DIC observation is very
high. Be careful, in particular, not to attach dirt or dust on
the sample surface.
· The detection sensitivity is direction-oriented. It is recommended
to use the rotational stage.
· Narrowing down the aperture diaphragm appropriately may
increase the contrast in some cases.
