Your Microscope
What is a Microscope?
The microscope is made of two lens systems:
the eyepiece and the objective. We're present-
ing these systems as one lens each, so that it's
easier to understand. In reality, however, the
eyepiece (1) and the objective in the turret (3)
are made up of multiple lenses.
The lower lens (objective) magnifi es the pre-
pared specimen (e.g. 11), which leads to a
magnifi ed image of the specimen. The picture,
which you can't see, is magnifi ed once more by
the second lens (eyepiece, 1). Then, you can
see the "microscope picture."
Assembly and Location
Before you start, choose an ideal location
for using your microscope. On the one
hand, it's important there is enough light
(normal observation). On the other hand,
it's important that you can quickly make
the room dark when you want to (projector
observation). Furthermore, I recommend that
you place the microscope on a stable surface,
since you won't be able to get any satisfactory
results on a shaky surface.
Normal Observation
For normal observation, place the microscope
in a bright location (near a window or desk lamp,
for example). Remove the microscope from the
packaging and tilt the microscope arm (9) so
that it's in a comfortable viewing position for you.

The focus knob (2) is turned to the upper stop
and the objective turret (3) is set to the lowest
magnifi cation.
Now,
through the eyepiece
and adjust the mirror (5)
so that you get a uni-

formly bright circle of
light. Or, you can use
the lamp. You'll fi nd fur-
ther tips about the lamp
in the next chapter.
