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 ﬁeld of vision as possi-

ble, while excluding as much of the black edge

of the ﬁeld of vision as possible. To do so, the

magniﬁcation 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 magniﬁcation. This primar-

ily avoids the critical border area of the ﬁeld of

vision and concentrates on the center of the

ﬁeld 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.
