Overview fixture 2.5x–4x
The overview fixture is for full display field
illumination when using an objective with a weak
magnification factor (2.5x–4x) in combination with
the Abbe condenser 0.0/1.25 H (424227-9000-
000).
It can be centered and remains swiveled into the
beam path for as long as the respective objective is
in use.
Swivel overview fixture (Fig. 2-21/
2
) into/out
of the beam path with the aid of a handle
(Fig. 2-21/
1
). Ensure that the overview fixture
snaps in securely when swiveled in.
The illumination of weak objective magnifications
can be centered with the centering screws. For this
purpose, the condenser should be centered on the
other objectives without the overview fixture.
With the overview fixture attached it can be mounted on the luminous-field diaphragm
operating unit, provided the condenser carrier is shifted as far down as possible!
