1. What is a microscope?

The lower lens (objective) produces a magnified image of the prepared
specimen. The picture, which you can't see, is magnified once more by
the second lens (eyepiece, 1), which you can see as the 'microscope
picture'.
2. Assembly and location
Before you start, choose an ideal location for using your microscope. It's
important that you choose a spot with enough light for normal observa-
tion. Furthermore, it is recommended that you place the microscope on
a stable surface, because a shaky surface will not lead to satisfactory
results.
3. Normal observation
For normal observation, place the microscope in a bright location (near
a window or desk lamp, for example).
Turn the focus knob (2) to the upper stop, and set the objective turret (3)
to the lowest magnification.
Now, turn on the light using the switch on the microscope base. You'll find
further tips about the light source in the next section. Now, place a pre-
pared slide under the clips on the stage (4), directly under the objective
(1). When you take a look through the eyepiece, you can see the magni-
