1. What is a microscope?
A microscope contains two lens systems: the eyepiece and the objective. We're presenting these systems
as one lens each so that the concept is 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) produces a magnified image of the prepared specimen (10). The picture, which
you can't see, is magnified once more by the second lens (eyepiece, 1), which you can see as the 'micro-
scope 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 observation. Furthermore, it is recommended that you place the micro-
scope on a stable surface, because a shaky surface will not lead to satisfactory results.
