the front surface.
◦ Rear surface tracking: the middle of the groove is positioned at a constant distance from
the rear surface.
◦ Distributed groove: the middle of the groove is positioned in proportion to the thickness of
the lens, with respect to the front surface.
◦ Lens curve tracking: the camber of the groove is adjustable.
