Optical Section

4.3.1 Overview

The basic function of the Optical Section is to project an enlargement of
the image on the microfilm onto the Screen when in the Reader Mode and
onto the CCD when in the Scan Mode.

There is a unique light path formed in each of these modes.

The light path formed in the Reader Mode is called the Reader Path and
that formed in the Scan Mode is called the Scan Path.

Each light path is formed by two Reader Path Mirrors and three Scan path
Mirrors.
