6.5 Installation of Condensers

All condensers of the Leica DMI series are equipped with a 7-position turret disk that can be equipped with light rings phase contrast (PH) or dark field (DF), IC prisms for transmitted-light interference contrast (DIC) or slit illuminators for integrated modulation contrast (IMC).

Light rings, slit diaphragms and condenser prisms are generally already installed in the turret at the factory, making the following assembly steps unnecessary. Please continue on → page 41, Installation of Condensers.

Installing the light rings and slit diaphragms

¥Switch the microscope off.

¥Remove the condenser cover (38.1). Insert the light ring in one of the condenser diskÕs large receptacles with guide grooves.

¥Turn the right-hand centering screw back fully with the adjusting key (39.2). To prevent the condenser disk from turning further, insert

the adjusting key (39.2) into the left-hand centering screw of the disk. It may protrude a maximum of 1 mm into the opening.

Insert light rings for Phaco (marked with the ID numbers 0, 1, 2, 3 and the focal intercept S of the corresponding condenser head), DF diaphragms (marked with a D for dark field and the focal in- tercept S of the corresponding condenser head) and slit diaphragms (marked M05, M10, M20, M40 and M63) in the location holes of the turret disk as follows:

¥Select a position and ensure that the two mounting screws have been released to the point that they no longer extend into the posi- tion. To adjust the screws, turn the desired light ring position into the beam path. You can now turn the screws using the two adjusting keys.
