Why Frictionless Air Bearings Enable Precise Force Control & Position Control Applications

Motion control systems, which typically control the position of stage or actuator, are sometimes tasked to provide both position and force control. These systems work in a dual mode, where the motion controller either controls the position or the force applied. In force-control mode, the motion stage must apply a controlled force while the position can…

How to Use Hexapod 6-DOF Motion and Positioning Systems

Hexapod positioning systems (Stewart Platforms) are versatile tools for multi-axis positioning and motion simulation applications. Hexapods provide 6 degrees of freedom and a user programmable center of rotation (pivot point) that allows extraordinary flexibility in alignment applications. Read more

Already in Orbit: PI Space-Qualified Series Systems for LEO Satellites

Tip/tilt mirrors for beam stabilization are essential subsystems for free-space optical communication networks. With the rapid development of LEO (Low Earth Orbit) satellite networks, the need for such subsystems is growing rapidly. Tip/tilt mirrors from Physik Instrumente (PI) have already proven their space qualification on several occasions. Now, they are proving their value in various satellite…

System with 6 Degrees of Freedom for Aligning Fibers and Optical Components

The basis of the fiber alignment system is a very stiff setup with an H-811 hexapod and an P-616 NanoCube® nanopositioner. The parallel-kinematic design for motion in degrees of freedom ensures high system stiffness. The motorreed drives make longer travel ranges possible and at the same time, the NanoCube® nanopositioner ensures fast scanning motion and dynamic compensation of drift…
