Ryf Axio Lab.A1 - Fig. 2-9 Setting the Viewing Height on the Binocular Tube; Fig. 2-10 Binocular Ergo Photo Tube 8-38°;20 with Fixed Graduation 50:50

DESCRIPTION OF THE INSTRUMENT
Carl Zeiss Control and functional elements on optional components Axio Lab.A1
38 430037-7144-001 04/2013
Interpupillary distance and viewing height
In all tubes:
 The interpupillary distance can be varied by
adjusting the eyepiece sockets relative to one
another.
 The viewing height can be varied by
swiveling the eyepiece sockets up
(Fig. 2-9/A) or down (Fig. 2-9/B).
For polarization microscopy we
recommend the photo tube Pol with
upright crosshairs.
Binocular ergo tube/ergo photo tube 8-38°/20
These tubes are designed for a field of view of 20.
The viewing angle can be continuously adjusted
between 8° and 38° by swiveling the binocular
section (Fig. 2-10/1).
The splitting ratio of the ergo photo tube is 50:50,
i.e.: 50 % of the light is directed to the eyepieces
and 50 % to the camera port.
CAUTION
The binocular ergo tube/ergo photo tube 8-38°/20 may only be used on the Axio Lab.A1 with
the base plate (430037-9100-000) installed, as the mi
croscope is otherwise liable to tip over,
resulting in damage to the instrument or injury to the user.
