6.3Installation 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 be- low the objective turret (Fig. 10b). Motorized, manual coded and manual DIC disks are avail- able. 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 ob- jective 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 3mm hex screwdriver, then tighten both Allen screws.

Note: insert the prism disk with the electron- ics board facing down. Do not touch the elec- tronics (especially the contacts) with your bare fingers!

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 tension. Insert the prism so that its identifying letter, e.g. ID, is facing upward and is legible.

¥After installing the prisms, replace the prism disk in its receptacle.
