`Depth of focus' is already a technical term that is in use. It refers to
the "depth of field" at the film plane, i.e., how much the film can be out
of perfect alignment and still capture an image in focus. Teaching students
terminology that is contrary to widely accepted standard use is probably not
a very good idea.
