Stewart Platform 6-Axis Robotics Hexapod Stage for Vacuum

POSTED 11/19/2021

A compact Stewart Platform Multi-Axis stage for precision positioning, based on the parallel kinematic hexapod principle was added to PI's hexapod family.  The H-811.iV vacuum compatible miniature 6-axis hexapod stage is a multi-axis positioning system with high resolutoin motion in a very compact package. Hexapod multi-axis stages are often used in active optical alignment and silicon photonics applications due to their versatility, precision and responsiveness.  A programmable pivot point allows the user to adapt the motion system to any alignment application quickly without retooling.  The mini hexapod has a load capacity of 11lbs and provides a maximum linear travel range of 34mm and maximum rotational range of 42 degrees.  The position repeatability is ±0.06µm.   Additional technical data are available on the H-811 vacuum hexapod product specifications page.
