DIC slider (U-DICRH), combine with the polarizer (U-POTP3).
· When using the mercury lamp housing, be sure to use the
L42 filter (U-25L42) to prevent the polarizer from tarnish.

If the DIC slider is engaged in the light path, remove it from the light
path. For details, see "4-8 Inserting the DIC slider" (page 44).

Engage the 10X objective or 20X objective in the light path and bring
the sample into focus approximately.

If the cover or the dummy slider is attached to the analyzer insertion
slot a or the polarizer insertion slot b , remove it.

Turn the analyzer rotation dial to adjust the analyzer.
Observation with crossed Nichols*:
Set the index of the dial to the
position shown in the picture on the
right.
Observation without crossed Nichols*:
Turn the dial while looking at the observation image and align it with
the position where you can view the desired observation image.
*
The crossed Nichols means the state that the field of view becomes the
darkest.
During DIC observation, the analyzer rotation dial must be set

to the crossed Nichols state.
Using the connection plate (BX3M-RLA-S/BX3M-KMA-S)
Connecting the polarizer (U-PO3 or U-POTP3) c and the analyzer d
to the provided connection plate e with the clamping knob allows
you to attach or detach the polarizer and the analyzer at the same time.
The connection plate cannot be used with BX3M-URAS-S.
