Applications
Automated scanning and mapping
Step-and-acquire across areas far wider than a single field of view.
Repeatable production indexing
Move parts between fixed stations with closed-loop encoders holding position over long shifts.
Programmable multi-axis motion
Coordinate several axes from software for processing, inspection and test sequences.
