Depth of focus and focusing
The telecentric optics, which cause objects to be displayed with a constant
size regardless of how far away from the prism they are, have a depth of focus
which is sufficient to capture deep preparations.
The image definition is determined by the distance between the 3D camera
and the preparation.

Operating Instructions for the Acquisition Unit CEREC 3
If the camera is held at an oblique
angle to the prepared insertion axis,
the wall closer to the lens will be
registered with an undercut; the wall
further away from the lens will be
fully displayed, thus causing the
occlusal margin angle to be
presented unfavorably there and
obstructing the automatic margin
detection.
