OWIS positioning systems in digital-holographic 3D measurement technology

Direct drive linear stages with resolution in the sub-µm range

In the HoloAMS optical 3D measuring stand developed by Fraunhofer IPM for the automated processing of customer-specific measuring tasks, the predefined measuring fields on the component surface are approached, recorded and then combined to form an image. The high-precision positioning of the component in the x-y plane required for this is achieved with two LINPOS M direct-drive linear stages and the PS 90+ position controller. Thanks to the powerful direct drives and the fine-resolution, incremental linear measuring systems, this setup guarantees high dynamics with maximum positioning accuracy and stability. The lateral resolution is in the sub-µm range.

Precision and reliability play a decisive role

At an on-site project meeting, Managing Director Rüdiger Ruh and Head of Development Dr. Peter Hilgers were impressed by the overall system: “We are delighted that we were able to convince the project team at Fraunhofer IPM with the performance and quality of the OWIS components”. In addition to precision and dynamics, reliability and fail-safety also played a decisive role in the selection and combination of components. These are important prerequisites for continuous operation in industrial production control.
