® Nano Drive Technology Based on a new ultrasonicceramic drive, they are light,
compact, self-locking, vacuum
compatible and have a number
of other advantages over clas-
sical
linear motors. Non-contact and absolute-measuring, with subnanometerresolution, excellent linearity
and high bandwidth. Ideally
suited for parallel
metrology
configurations. Monolithic multilayer piezoactuators with ceramic encap-
sulation. Insensitive to atmos-
pheric humidity, longer lifetime
and wider operating tempera-
ture range than conventionalmultilayer piezo
industrial actuators.Ideal for vacuum operation. Addresses the drawbacks of existing nanopositioning drives.Provides long travel, subnano-
meter resolution and very high
forces. Non-magnetic, UV- and
vacuum compatible. electrode designs. Active Trajectory Control Dynamic Digital Linearization Compensates crosstalk andguidance errors achieving ac-curacies in the subnanometerand submicroradian range. Reduces phase shifts and track-ing errors of piezo nanoposi-
tioning systems used in fastscanning applications. Im-proves dynamic linearity by up
to 1000-fold. Parallel Kinematics /Hexapods Parallel Metrology Design Allows design of compact, stiffmicro- and
nanopositioning stages with minimal inertia for
fastest possible response; no
cumulative guiding error and
no moving cables. Permits better multi-axis accu-racy by keeping all motion onall controlled axes inside the
servo-loop. Parallel metrology
is a requirement for active tra-
jectory control. InputShaping >
® Piezo Controllers Stops self-excited vibrationsinside or outside the servo-loop
before they start. Achieves
fastest possible settling—usu-
ally within one period of the
resonant frequency. >
