Installation Of The Dic Module; And Dic Objective Prisms - Leica DMI Series Instructions Manual

6.3 Installation of the DIC Module

and DIC Objective Prisms

If your microscope is not equipped with DIC,
please continue with Chapter 6.4.
In the Leica DMI series microscopes, the DIC
prisms are already installed in the DIC disk below
the objective turret (Fig. 10b). Motorized, manual
coded and manual DIC disks are available. The
installation is identical for all types.
Proceed as follows when making changes to the
IC prism disk:
• Remove the front cover (Fig. 11) below the
objective revolver after releasing the socket
screws (Fig. 10a).

• Insert the DIC prism disk (Fig. 10b) squarely in
its receptacle. First, lightly tighten one screw
with the included 3 mm hex screwdriver, then
tighten both Allen screws.
Note: insert the prism disk with the electronics
board facing down. Do not touch the electron-
ics (especially the contacts) with your bare fi n-
gers!
Replacing Individual IC Prisms:
• Release the two socket screws and remove
the prism disk.
• Place the prism against the stop pin (10b.3),
place the washer between the screw and the
prism, and tighten gently to prevent undue ten-
sion. Insert the prism so that its identifying let-
ter, e.g. ID, is facing upward and is legible.
• After installing the prisms, replace the prism
disk in its receptacle.
