Vacuum-compatible hexapod
Our hexapods for environments down to 10−6 mbar
Vacuum and high-vacuum compatible hexapods
High-precision positioning in extreme conditions
Symétrie hexapods are specially designed for applications requiring precise positioning in vacuum or ultra-high vacuum environments, down to 10⁻⁶ mbar. These multi-axis systems deliver stable, repeatable performance where atmospheric conditions do not allow it.
High vacuum limits contamination, oxidation, and mechanical disturbances, ensuring reliable measurement and high-precision metrology.
A design adapted to high vacuum
Our vacuum-compatible hexapods feature:
- Low outgassing materials, selected for their chemical and mechanical stability, particularly on cables,
- Vacuum-compatible lubricants, ensuring smooth movement without particle emission,
- High vacuum-compatible motors and sensors, guaranteeing precise movement control.
Each component is optimized to withstand the thermal and physical stresses inherent in vacuum environments, while maintaining submicron positioning stability and accuracy.

FAQ
What kinds of movements can the Symétrie hexapod perform?
The hexapod can perform combined movements across its six degrees of freedom: three translations (X, Y, Z) and three rotations (Rx, Ry, Rz). This flexibility allows for complex adjustments that would be impossible with conventional guidance systems.
What is the accuracy or resolution of the movements?
Our hexapods achieve resolutions of around 0.1 µm for linear motion and a few microradians for rotational motion. Repeatability is one of our key strengths, ensuring the accuracy of every positioning operation.
What materials are used to make the hexapod?
We use high-performance materials such as anodised aerospace-grade aluminium, stainless steel and components specifically designed for demanding environments (vacuum, cleanroom, non-magnetic).
Is it compatible with different software or control systems?
Absolutely. We provide function libraries (SDKs) compatible with LabVIEW, C++ and Python, as well as specific interfaces for research environments such as EPICS and TANGO.
Is the hexapod safe for use in laboratories or in industry?
Safety and reliability are at the heart of our design. The software features configurable travel limits, virtual collision detection and hardware safety features to protect your equipment and samples.
