Leica M80 - Photo Tubes and C-mounts

Leica M-series User Manual 45
Photo Tubes and C-mounts
Application
All Leica DFC cameras are equipped with a
standardized C-mount interface. In turn, the
C-mount adapter for the respective trinocular
tube is connected to this interface. This adapter
creates a solid mechanical connection between
the microscope and camera and ensures opti-
mum rendering of the microscopic image on
the image sensor of the camera.
Usually, the ideal is for the digital camera to
capture as much of the eld of vision as possi-
ble, while excluding as much of the black edge
of the eld of vision as possible. To do so, the
magnication factor of the C-mount adapter
must match the image format of the sensor as
closely as possible (see table).
If there is unwanted shading at the corners even
with a compatible C-mount adapter installed, it
can be corrected using the "Shading function"
of the camera software.
Alternatively, you can also use a C-mount
adapter with higher magnication. This primar-
ily avoids the critical border area of the eld of
vision and concentrates on the center of the
eld of vision.

Cameras from third-party suppliers
In addition to Leica DFC cameras with the stan-
dardized C-mount interfaces, you can connect
third-party cameras to the microscope using
a T2 bayonet adapter. To do so, instead of the
C-mount adapter, simply use the correspond-
ing SLR adapter with T2 connection. However,
these third-party cameras are not integrated
into the Leica Application Suite and have to
be operated using the corresponding software
from the camera manufacturer.
The Leica digital cameras are detailed in a sepa-
rate user manual along with instructions for
their assembly and use.
