4D dynamic interferometers play critical roles in the development and production
of hard disk drives. 4D systems measure the flatness and surface
shape of magnetic media, including both sides of glass media in a single
setup. |

Fast acquisition enables measurement of spinning disks, to accurately
assess the performance of spindles, hubs, motors and media.
Capable of measuring in the presence of significant vibration and air turbulence,
4D systems are equally at home in the lab or clean room, or on the production
floor.
