Attaching the DIC Prisms (for Revolving Nosepiece)
(Fig. 34)
}The DIC prisms for use in the revolving nosepiece include the WI-
DICTHRA2 (high-resolution type) and WI-DICT2 (middle-contrast type). The
revolving nosepieces in which a DIC prism can be inserted are the WI-
SRE3 and WI-SNPXLU2.
The DIC prisms (WI-DICT or WI-DICTHRA) cannot be attached to the
revolving nosepieces (WI-SRE3 or WI-SNPXLU2) because of their shapes
and sizes.
1. Remove the revolving nosepiece from the revolving arm, then fully loosen
the drop prevention screw
1
with a Phillips precision screwdriver.
2. Hold a DIC prism
2
with the side with indications facing up, and insert it
by aligning the positioning pin
3
with the groove
4
on the revolving
nosepiece.
After the insertion, tighten the drop prevention screw
1
securely.
3. Attach the revolving nosepiece onto the revolving arm.

Attaching the DIC Prisms (for Condenser)
(Figs. 35 to 38)
}DIC prisms can be inserted in three types of condensers including the WI-UCD, WI-DICD and U-UCD8*.
* Do not use the U-UCDTP530 one-wave plate for the U-UCD8 but use the exclusive WI-TP137 quarter-wave plate.

Application
CCD observation
(Surface to deep)
Observation of relatively shallow area
(0 to 100 µm)
Observation of relatively deep area
(50 to 150 µm)
Optimum for surface layer observation.
DIC prism (for condenser)
List of DIC System Combinations
** The actual view is equivalent to the middle-contrast type because of lower magnification and higher NA than usual.
Binocular observation
(Surface layer only)
Less suitable for surface layer observa-
tion than the high-resolution type.
