Leica M-series User Manual 53
The ring illuminator, the Leica LED5000 RL
("Ring Light"), is installed on the objective using
a single screw. It has been optimized for a work-
ing distance between 60 and 70 mm.
Constraints
The Leica LED5000 RL can be used in conjunc-
tion with the planapochromat 1× and planapo-
chromat 0.63× objectives. With all other
objectives, the working distance is too low for
adequate illumination.
The ring illuminator cannot be used together
with the objective nosepiece.
Assembly
1. Connect the CAN-bus cable to the ring illu-
minator. The flat part of the plug must be
facing upwards.
2. Push the ring illuminator over the objective
as far as it will go and screw it into place.
3. Plug the other end of the cable into one of
the two "CTL2" sockets on the column.
For optimum accessibility of the specimen,
the ring illuminator should be installed with
the cable facing backwards. However, it is
also possible to turn the ring illuminator side-
ways, for example if simultaneously using the
Leica LED5000 MCI™ system illumination. In this
case, the ring illuminator cannot be connected
directly to the Leica LED5000 MCI™.
