The F-206.S Hexalign system can be used in complex, high-accuracy positioning and alignment tasks where independent, high-precision motion in six degrees of freedom is required.

The six-axis alignment system from PI provides 6D motion with 33nm resolution and advanced alignment software for optics and photonics components.

It includes an advanced parallel kinematics controller/driver featuring vectorised motion with arbitrary pivot-point capability, as well as an extensive software package.

The parallel-kinematics design with a virtual pivot point and vector-based 6D motion-controller means that the F-206.S system differs from conventional stacked multiaxis positioners.

Due to the reduced moving mass – only one common lightweight platform for all six actuators – the system can respond and settle much faster.

It is also said to be considerably more compact and accurate than conventional multi-axis stage stacks.

Its parallel-kinematics design and advanced, digital 6D controller minimises unwanted crosstalk motion.

The F-206.S Hexalign system is based on the virtual-pivot-point capability built into the controller.

Since Hexapod motion is not determined by fixed bearings but real-time, six-space control algorithms, this point can be chosen freely with a single software command – a prerequisite for fast and accurate alignment tasks.

Software for automatic optical alignment: the Hexapod comes with powerful control and alignment software, Labview drivers, DLLs and several programming examples.

When equipped with an optional high-speed photometer card, the Hexapod is said to align arrays, waveguides and collimators up to 10 times faster than conventional multiaxis positioning stages.

Application examples: precision positioning, alignment and testing of optics, photonics and MEMS components in nanolithography, micromanipulation and microsurgery.
