PI (Physik Instrumente) L.P., a leading manufacturer of nanopositioning and precision motion-control equipment for optics, nanotechnology, photonics, semiconductor and life science applications, offers has designed a unique high-load Hexapod for astronomy applications and other alignment tasks.
The high-load Hexapod combines extremely high precision with a load capacity of up to 1000 kg. It provides minimum incremental motion to 0.8 µm and 1 µrad, respectively. The six individual actuators have a design resolution of 0.08 µm and a stiffness of 40 N/µm.
Features:
- 1000 kg Load Capacity (Vertical)
- Six Degrees of Freedom
- Works in Any Orientation
- No Moving Cables for Improved Reliability and Precision Repeatability to 0.5 µm Actuator - Resolution 0.008 µm Vacuum-Compatible Versions Linear and Rotary Multi-Axis
- Scans Virtualized Center of Rotation (Pivot Point) Sophisticated Controller Using Vector - Algorithms Heavy-Duty, Ultra-High-Resolution Bearings for 24/7 Applications
- Hexapod Working Principle and Advantages:
The M-850 Hexapod is driven by six high-resolution actuators all connected directly to the same moving platform. The principle is similar to that seen in flight simulators, but considerably more precise. In place of the hydraulic actuators used there, the M-850 uses custom high-load precision screws and servo-motors. It can withstand loads of 1000 kg vertically, and at least 180 kg in any direction.
