Adaption of the slide overlay device and the
macro dual system
With the Leica DM IRB inverted microscope, the
slide overlay and macro devices can only be
adapted onto the FSA 25 PE tube.
This tube has a side flange (44.1) for mounting
the reflection optics. These reflection optics are
used for mechanical and optical adaption of the
slide overlay device and the macro dual zoom
system.
The slide overlay device consists of the
reflection optics (44.2), the illumination unit with
6 V 4 W halogen lamp (44.8), the standard
5 x 5 cm slide holder (44.6) and the control (44.5)
for focusing the slides. The halogen lamp is
powered by a separate transformer (Fig. 45).
Mount the reflection optics (44.3) onto the tube
flange (44.1) with the coupling ring (44.2),
ensuring that the guide pin engages in the
groove, and screw down. In the same way,
screw the slide overlay device with coupling
ring to the reflection optics, again watching the
position of the guide pin.
