2.6 Operation and Functional
Elements of Optional
Components
2.6.1 Phototube and Intermediate
Phototube
Using appropriate adapters, you can attach reflex
cameras, microscope cameras and video cameras
to the camera port (Fig. 2-10/1 or Fig. 2-11/1) of
binocular phototubes.
Binocular Phototube 45°/23 or Binocular
Phototube, Left, 45°/23, with Fixed 50:50
Division
Fifty percent of the light is directed to the
eyepieces, while the other fifty percent is directed
upward to the camera port on top (Fig. 2-10/1) or
to the left (Fig. 2-10/2).
Through the eyepieces, external light sources
present in the room may affect the image on the
camera (contrast degradation or even imaging of
the light source). To obtain artifact-free images,
use the dust caps provided for the eyepieces.
Intermediate Phototube Left
Using an exchangeable slider (Fig. 2-11/2) and the
intermediate phototube, you can direct the light to
the eyepieces, to the camera attached on the left-
hand side or to both simultaneously. For this
purpose, you may install either the beam-splitting
mirror or the mirror.
The slider itself is supplied with the phototube. The
beam-splitting mirror and the mirror are each
available separately.
The sliders feature two positions each.
If the microscope is fitted with a 50:50 beam-
splitting mirror:
− Position 1: 100 % of the light directed to
eyepieces
− Position 2: 50 % of the light directed to
eyepieces and 50 % to camera
If the microscope is fitted with a 0:100 mirror:
− Position 1: 100 % of the light directed to
eyepieces
− Position 2: 100 % of the light directed to
camera
