Adjusting individual interpupillary distance by
symmetrical swiveling of the two eyepiece
sockets against each other (Fig. 3-34).
The correct interpupillary distance has been set

Setting the viewing height
x
The viewing height can be adjusted to
individual requirements by swiveling the
eyepiece sockets up (Fig.
3-35/
A
) or down
(Fig. 3-35/
B
).
This individual height adjustment in two stages
(upper and lower position) is basically possible with
all tubes of the Axio Lab.A1 program. The viewing
height difference thus achieved depends on the
selected interpupillary distance and the tube
viewing angle, which may be stationary or variable,
depending on the model. With an interpupillary
distance of 65 mm and a tube viewing angle of
30°, this adjustable height difference is approx.
40 mm.
Binocular ergo (photo) tubes (425511-0000-000,
425512-0000-000, 425514-0000-000, 425520-
9050-000) are provided with continuous height
adjustment in the range 44 mm or 50 mm.
The binocular part of the ergo photo tube 425520-9050-000 is also continuously horizontally retractable
up to 50 mm.
The eyepoint angle of binocular ergo (photo) tubes (425522-9020-000 and 425522-9030-000) is
continuously adjustable in the range 8° to 38°.
The comfortable binocular ergo tube (425522-9040-000) is continuously height-adjustable by up to
50 mm and angle-adjustable from 8° to 33°. This is the ergo tube which received the highest distinction
and recommendation in terms of ergonomics at the microscope workstation within the scope of the TÜV
certificate of economics.
