Piezo Tubes Ensure a Higher Image Resolution in Scanning Fiber Endoscopy

In medicine, finest endoscopes are not only being used for diagnostics but also more and more frequently for the therapy of illnesses. Thanks to their compact and flexible design of just a few millimeters diameter, they ensure even gentler minimally invasive procedures. Contrary to the limitations of the image quality of common endoscopes, the new innovative design of scanning fiber…

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 vary. In position control…

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…
