The divering lens has focal points at f1
http://physics.bu.edu/py106/hwex/hw8/node9.html WebA ray entering a diverging lens parallel to its axis seems to come from the focal point F. A ray passing through the center of either a converging or a diverging lens does not change direction. A ray entering a converging lens through its focal point exits parallel to its axis.
