The M-824 Hexapod 6-Axis micropositioning and alignment system from nanopositioning specialist PI provides high resolution motion in 6 degrees of freedom. It is designed to work in a vacuum and combines multiaxis motion to 45 mm (linear) / 25 degrees (rotation) with sub-micron resolution and repeatability–ideal for alignment an precision positioning tasks.

The greatest Hexapod advantage is its compact size compared to conventional six-axis positioning systems, a fact that is especially beneficial in applications in vacuum chambers, where space is at a premium.

Typical Applications: Semiconductor technology, multi-axis alignment of optics,
X-ray microscopy, X-ray monochromators.

General Features & Advantages of Hexapods:
Compared to conventional stacked "serial" kinematics 6D micropositioning
systems the Hexpod (parallel kinematics) approach has the following advantages:

• Smaller Envelope for Easy Integration
• Higher Stiffness and Minimized Inertia for Faster Response and Alignment
• No Moving Cables (No Friction) for Increased Reliability and Repeatability
• Center of Rotation can be Changed with One Software Command
• No Accumulation of Runout Errors—Better Multi-Axis Repeatability
