Dynamic Referencing, No Markers Needed

The FreeTrak bar dynamically tracks the TE25 scanner thanks to its tracking targets, without the need to manually place markers on the scanned object. This markerless operation saves time and makes the 3D scanning process much smoother.


The FreeScan Trak Pro2 Portable Optical Coordinate Measuring System is the ideal metrology tool for quality control and 3D inspection. With high precision and repeatability, the FreeScan Trak Pro2 allows for fast, accurate inspection of various part types and surfaces without the need for markers.
When paired with the optional FreeProbe, users can seamlessly integrate contact probing to the optical scanning process for a swifter and more convenient overall inspection workflow.

50 crossed laser lines: Quick and highly accurate scan
7 parallel laser lines: Partial HD scan for extremely fine details
1 single laser line: Deep hole scanning (hole diameter:depth ratio of 1:4)

Supports both optical tracking and marker scanning

FreeScan Trak Pro2 delivers metrology-grade scanning results with exceptional accuracy, reaching up to 0.023mm.

*Based on VDl/VDE 2634, sphere-spacing error is assessed with traceable length artefacts and markers by measuring these at different locations and orientations within the working volume, in the accuracy lab certified with ISO/IEC 17025:2017 with environment conditions: temperature 20 ± 0.5℃; humidity 40 ~ 60% RH.

FreeScan Trak Pro2's wide and expandable tracking range allows measurement of a broad spectrum of volumes and surfaces without compromising accuracy or requiring traditional leapfrogs in the scanning process.

Robust & Intuitive Software

Real-time Display of Mesh Data

Our intuitive, streamlined software displays mesh data in real time as you scan your workpiece, saving time on point cloud meshing later on.

Data Quality Visualization

Users can determine if the scanning distance is appropriate by observing the color of the laser lines projected onto the object. There is also a built-in data quality indicator to determine which parts of the data are insufficient.
