Attach the L-DIHC/L-DIC DIC slider to the quintuple
nosepiece (MA2-NUI5 or LV-NU5A) in combination
with the MA2-PA polarizer/analyzer unit to perform
the DIC microscopy under the episcopic illumination
in single NR method.
The L-DIHC slider is designed for high contrast
observation.

Setting the DIC prism
Figure 3.15-3 DIC prism position indication
For the DIC microscopy, switch the DIC prism
depending on the objective to be used.
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. The figure shows the character “A” indicated
on the objective. Turn the prism setting dial to align
the index with the “A”.
