I've seen in several times when referring to the length of a lens. What distance is that exactly?

 

Example from the a Schneider Xenon 18mm Lens:
Full Length: 133 mm

Front to Flange: 122mm

Does anybody know?

What I take is that the full length is the overall length of the lens from end to end (I assume when focused at infinity), while front to flange is  from the front to the flange on the lens mount i.e. how far the lens will stick out from the camera.
