Observation Method
1. Place the specimen on the stage and adjust the focus by moving the
stage up or down.
2. Adjust the field iris diaphragm so that its image circumscribes the field of
view.
3. The contrast may sometimes be enhanced by closing the aperture iris
diaphragm slightly.
U-DICR, U-DICRHC
1. Adjust the background contrast by turning the slider movement knob |
on the DIC slider as described below. (Fig. 12)
2. When the slider movement knob on the DIC slider is turned, the interfer-
ence color in the background varies continuously from the gray sensitive
color to magenta sensitive color (from -100 to 600 nm). Set the interference
color which can provide best contrast with respect to the specimen.
· 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.
