INSTRUCTION MANUAL
The total magnification can be calculated by multiplying the magnification of the eyepiece
with the magnification of the objective. The magnifications are displayed in the table below:

Object stage
On the basic models the slide is placed beneath the object clips. On the other models into
the clamp of the mechanical stage (G) and can be carefully moved into X- and Y- directions.
Focusing the specimen is done by using the coaxial coarse- and fine adjustment knobs (I).
Coarse- and fine adjustment
The coarse- and fine adjustment knobs (I) for the height adjustment of the object stage are
mounted together on one (1) axle (co-axial). On both fine adjustment knobs there is a gradu-
ation with intervals of 0.002 mm. This can be used to measure depths in a specimen.
Abbe condenser with iris diaphragm
Beneath the object stage an Abbe condenser (M) N.A. 12.5 is mounted. The condenser can
be adjusted in height by means of turning. With this one can focus the light on the specimen
by which the contrast can be optimised. The condenser is factory pre-centered.
The iris diaphragm with filter holder is mounted beneath the condenser. The light intensity
can be adjusted by changing the flexible opening.
