The target moves.
Ensure that the tripod is within the centering chamber.
Use the recut lens tripod (option) for a high base lens, a recut lens or a decentered lens (option).
Position the lens on the tripod.
Slowly move the lens until the manufacturer markings are:
• Perfectly centered in the centering cross,
• Parallel with the horizontal lines.
The lens is now centered and ready for blocking.
To carry out lens blocking, refer to the section Lens Centrering > Blocking a lens (F p.61).
