Construction of the microscope:

Objectives:

All objectives are produced accor-
ding to DIN-standard. 40x and 100x
objectives have a spring mount to
avoid breakage of specimens and
objectives. The five-hole objective
revolver makes it easy to change
between the different objectives. 

Focusing knobs and stage stop
adjustment:

The coaxial coarse and fine adjust-
ment knobs make it easy to attain a
sharp image. The biggest knobs are
used for the coarse adjustment and
the smallest knobs for the fine adju-
stment. 

Between the left large focusing
knob and the column is there also a
ring. With this ring it is possible to
adjust the friction when turning it. In
this way it can be adapted to diffe-
rent users’ wishes. 

On the right side (between the right
large focusing knobs and the colu-
mn) is a stop ring with a small peg.
This is called the stage stop. With
this ring it is possible to settle the
upper limit of the stage movement
to protect the specimen from
 touching and/or damaging the ob -
jectives. Furthermore, the stop ring
will make you able to focus more
quickly. The stage stop ring is loo-
sened by turning the ring towards
you/down, when you are sitting in
front of the microscope. 

Mechanical stage:

The specimen is placed on the
mechanical stage by pulling back
the movable handle of the speci-
men holder. Gently release the
handle and the specimen is placed
securely. The mechanical stage can
then be moved in the X and Y-axis
with the coaxial mounted knobs
under the right side of the mechani-
cal stage.
