Operation for the DIC Prism
When the motorized DIC nosepiece (LV-MDIC) is installed, the DIC indicator lights up. In this
setting, the DIC prism (Nomarski prism) position in the motorized DIC nosepiece can be adjusted
by operating the +/- buttons in the DIC area.
Operation for the DIC prism
The DIC prism moves as described below by operating the
+/- buttons in the DIC area.
If the DIC prism is located at the limit and an attempt is
made to move the prism farther, a beep sounds.

The prism moves into the optical path.
The prism moves away from the optical path.
Operation for the motorized DIC prism
Interlock control of the DIC prism
When the interlock control function is enabled with LVSetup, the DIC prism condition changes in
accordance with the microscopy method and the selected objective.
•
DIC prism insertion/removal (interlocked with the microscopy method)
•
Position A/B selection (interlocked with the objective)
•
DIC prism fine adjustment position (interlocked with the objective)
If the DIC prism is operated manually after the interlock control, the DIC indicator blinks to show
that the prism condition is modified from the registered condition.
Selection between position A/B
To perform DIC microscopy, the DIC prism position must be selected between position A or
position B in accordance with the pupil position of the selected objective. “A” or “B” symbol is
indicated on the side of the objectives to show the pupil position.
When the motorized DIC nosepiece is used and the information of the objectives are registered with
LVSetup, the DIC prism position is moved to position A or position B automatically in accordance
with the selected objective.
To perform differential interference contrast (DIC)
microscopy with the DIC prism, a polarizer and an
analyzer must be located in the optical path. When the
LV-UEPI2A is used with the product, a polarizer and
an analyzer can be set in the optical path easily with
the PA block.
