9. Contrast methods for Leica DM4000 B/DM4500 P/DM5000 B

•Insert the analyzer on the left side of the stand up to the click stop (fig. 73).

•Then insert the objective prism slider into the slot on the objective turret.

•The DIC prism that needs to be used appears on the display.

•For fine adjustment, rotate the knurled screw (74.1) on the objective prism slide.

Alternatively:

•Manually rotate the polarizer on the underside of the condenser into the beam path (Fig. 72).

•Likewise, manually insert the analyzer up to the stop into the left side of the stand (Fig. 73). The objective and condenser prisms are auto- matically moved into the beam path.

•Switch to the transmitted light axis (TL) by pushing the TL/IL function key.

•Apply a specimen and rotate a suitable objec- tive into place.

•Select the DIC contrast method.

Do so by pressing the DIC variable key. Alternatively: press the variable button

CHANGE TL .

(For details on key assignments, please see the identification sheet.)

ICT appears on the display.

•The polarizer located in the condenser and the fitting condenser prisms are automatically brought into the beam path. The correspond- ing objective prism and the analyzer cube are also positioned automatically.

•For fine adjustment, use the knurled wheel above the objective turret.
