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 'microscope picture'.
