| Among PI’s products include
the world’s smallest piezo nanopositioning systems with integrated capacitive
sensors and flexure guiding systems. They provide sub-nanometric resolution
and settling times in the millisecond region, though they are hardly larger
than a cent. Stages of this caliber are predominantly found in the computer
disk-drive and fiber optic industries. A digital controller is used to
drive the ID chip equipped stages enabling optimum compensation and straightforward
interchangeability without the necessity for re-calibration. |
