® 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 subnanometer
resolution, excellent linearityand high bandwidth. Ideallysuited 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 conventional
multilayer piezo actuators.
Ideal for vacuum operation. Addresses the drawbacks of Single and dual existing nanopositioning drives.Provides long travel, subnano-
meter resolution and very high
forces. Non-magnetic, UV- and
vacuum compatible.
industrial electrode designs. Dynamic Digital Linearization Reduces phase shifts and track-ing errors of piezo nanoposi-
tioning systems used in fast
scanning applications. Im-
proves dynamic linearity by up
to 1000-fold. Active Trajectory Control Compensates crosstalk andguidance errors achieving ac-
curacies in the subnanometer
and submicroradian range. 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 on
all controlled axes inside the
servo-loop. Parallel metrology
is a requirement for active tra-
jectory control. InputShaping >

before they start. Achieves
fastest possible settling—usu-
ally within one period of the
resonant frequency. >
