The general situation:

A general surface, called S, has two focal sheets. Taken together, these focal sheets constitute the focal surface of the surface S.

Various degenerate situations:

Parabolic Disc Point Focus:

Parabolic Disc Point Focus – with transparency:

Double-Cylindrical Point Focus:

A description of the Double-Cylindrical Point Focus can be found at the Azimuth Project.
