tube 20°/23 and ergo photo tube
15°/23, each with continuous
vertical adjustment
These ergonomic tubes are designed for a field of
view of 23 mm. The viewing angle is 20° or 15°.
The ergo photo tubes are equipped with one
camera port each (Fig. 2-9/

and Fig. 2-10/

).
The camera ports can be used to mount a reflex
camera, a microscope camera or a video camera
with the aid of appropriate adapters.
The camera port can carry a maximum weight of
2.5 kg (camera plus cable). For a fee, the ZEISS
service personnel will equip your instrument with a
higher maximum load, if needed.
The ergo tubes permit a height adjustment range
of 44 mm.
A larger range can be obtained by swiveling the
binocular section from the lower to the upper
observation position (depending on the inter-
pupillary distance).
