The stand
There are 5 basic versions of the DM IRB stand,
which allow over 50 microscope variants to be
configured.
These 5 basic versions are:
– Manual or electronic stand
– With or without integrated fluorescence axis
– With or without SLR front port or bottom port
– Lateral photo port 100 % or 80 %
– With or without integrated magnification
changer
The variants and their components, differences
and uses will be explained individually in this
manual. The function and operation of all
microscopy techniques and the necessary
accessories for the Leica DM IRB will be
described and explained in detail in the Opera-
tion section of this manual.
First of all, here is a general overview:
Stands
The basic stand has a photo port on the left for
the adaption of: TV camera, SLR camera or
photomicro system. The variants offered send
either 100 % or 80 % of the light to this photo
port.
Besides the lateral photo port, the SLR stand
also has another port facing the front (front
port*) which can be equipped with either an
SLR camera or a TV camera with c-mount
connection.
The stand with bottom port cannot be equipped
with an SLR front port. This variant is only
produced at a customer’s specific request.
The electronic stand additionally offers a
motorised objective nosepiece, electronic
focusing, IC objective prism coding, LCD display
of microscope functions and (optional)
motorised filter cube changer (RF4-mot module)
with electric dark flap, control panel, etc. All the
above-mentioned stands are also available as
fluorescence stands with integrated fluores-
cence axis. All the fluorescence stands (in-
cluding the manual versions) can be fitted with
the RF4-mot module.
Tube mount
The interface between the stand and the tube is
called tube mount or tube change interface.
The tube mount is compatible with DM IR tubes
and the IR/R tube adapter which allows the use
of DM R tubes.
Tube
The tube, or its tube lens, produces the primary
image together with the objective.
DM IR tubes consist of a basic part, the
binocular part and the tube change ring. The
trinocular tube also has a photo/TV port. A
switchable mirror either directs the light 100 %
to the eyepieces or 100 % to the photo port, or
splits it 50 %/50 %.
