Physik Instrumente: Hexapod H-860

The H-860 is specifically designed to test the image stabilization function in camera systems, smart phones and camera modules. In contrast to the design of the Stewart-Gough platforms, PI has implemented a kinematic system based on the shifting of the joint positions.

The H-860 is based on PIMag® voice coil motors developed in-house. The special design with flexure joints and contactless magnetic drive principle has no friction or rolling parts for guides and joints and is therefore designed for maximum service life and uptime. A contactless linear encoder ensures reliable position control and high repeatability.

Innovation: The Hexapod H-860 is the only multi-axis system that achieves the required angular movements with the appropriate frequencies and repeatability to reliably test cameras, ensuring high image and video quality and supporting camera-based innovations.  The combination of highly dynamic linear motors and the lightweight design with highly rigid carbon milled parts allows fast and precise movements and high accelerations. The control is designed for dynamics and precision.

The parallel kinematics with a freely selectable coordinate reference system can be used flexibly, allowing camera or smartphone manufacturers, for example, to carry out more complex prototype tests.
