Mechanical brakes
Grobtrieb, condensor lens impulse and Binokulartubus contain en placable brakes.
Grobtrieb and condensor lens impulse
Both Triebknöpfe firmly cover. Left Triebknopf festhal ten, right Triebknopf in the clockwise direction turn: Course more heavily
against clockwise direction turn: Course more easily
Binokulartubus
The brake in the Binokulartubus ensures for it that the einge placed viewing distance of the connecting pieces of the Tubus remains and
itself not automatically changed. To placing the brake behind:
Connecting pieces of the Binokulartubus on closest viewing distance stel len, 2 groups of 3 screws each become visible
Small screws with screwdriver tighten: Course more heavily solve: Course more easily
The seat of the large screws may not be changed!

Swivelling Kreuztisch D
The table is work-centered and around 180° swivelling. For the rotation of the table the complex Y-vernier/clamp favourably screw (fig.
2/22, 23) as if handles use, thus do not even tuell stopped X/Y coordinates not to be adjusted.
With the clamp (fig. 2/22) the Y-impulse of the object of leader knows and with the clamp (fig. 2/23) can the table turn be locked.
Note! If the Y-impulse of the object leader over the work area for slide 26 x is adjusted 76 mm outside. Table carefully turn, so that it does
not fasten at the Stativsäule!

Table change
Clamping screws under the table (fig. 3/28) with hexagonal key (fig. 6/59) loosen. Table to the right schiebenund from the swallow
guidance take off.
The table, with which is to be now worked, in those swallow guidance of the table carrier (fig. 3/29) to attack to push in to the left
and with clamping screws clamp.

Condensor lens change
JENAVAL can be equipped - depending upon the microscopic work project - with different condensor lenses. Except achromatic
aplanatischer) condensor lens 0.9 the standard out arms are available:
aplanatischer condensor lens 0.9 (for transmitted light fluorescence) achromatic aplanatischer condensor lens head 1,3DF-Kondensor 0.12-
0.85 for dark field with objectives 6,3x/0,12 to 50x/0,80DF-Kondensor 1.2 for dark field with objectives 25x/0,50bis REAR ONE 100x/l,

Change against DF-condensor lens 0.12-0.85 and DF-condensor lens 1,2
Condensor lens with impulse lower, to clamping screw (fig. 3/30) becomes accessible. Clamping screw loosen. A trailers to the left
swing out and take out.
DF-condensor lens in appropriate way from left into the Schwal benführung use,
