3.15.3 Interference color
You can change the interference color continuously by turning the prism movement knob.
Interference color Characteristics
Dark color Observations similar to the dark-field microscopy can be performed.
Gray Phase contrast distribution of the whole sample with a bird’s eye view can be
observed.
Sensitive red-violet Observations with the highest color contrast can be performed.
3.16 Using the DIC Slider (LV-DIHC/LV-DIC)
Figure 3.16-1 LV-DIHC/LV-DIC Slider
The LV-DIHC/LV-DIC DIC slider is attached to
sextuple nosepiece revolver (D-ND6) in combination
with the MA2-UPA polarizer/analyzer unit for DIC
microscopy under the episcopic microscopy in
Senarmont method. The LC-DIHC is designed for
high contrast observation.
3.16.1 Selecting the DIC slider
Both the LV-DIHC and the LV-DIC sliders have A and B types to be selected, according to the objective.
The industrial LU objective has a character (A or B) showing the DIC prism position, which is indicated next to
the magnification/N.A. value on the objective barrel (refer to Figure 3.15-3). Select the DIC slider as indicated
on the objective. In Figure 3.15-3, the character “A” is indicated next to the magnification/ N.A. value. Use the
A-type DIC slider as indicated.
3.16.2 Inserting/removing the DIC slider from the optical path
Push the slider into the revolving nosepiece to the limit and the DIC prism enters the optical path.
To remove the DIC prism from the optical path, remove the slider from the revolving nosepiece.
