3D DIC Systems

Let's take a look beyond the second dimension 

Alpha Strain Analysis SW now measures in space. No, not the outer space, but in 3D. So let's dig in and measure some real challenges on complex specimen geometries. 

It is easier than ever to get the most from a single experiment.

For more info about the 3D software features see the bottom of this page.



The ultimate versatility and width of usage make FreeD a 'must have' for every R&D facility.

It can be equipped with a large variety of cameras, lenses, lights, and further optical accessories. 

  • Tensile - Axial / Transversal
  • Compression
  • Bending
  • Shear
  • Torsion

Stereo ONE

A 3D expansion of our industrial top-selling device opens an opportunity to measure specimens of complex geometry or specimens showing large out-of-plane displacement during the test.

Suitable mainly as an auxiliary sensor for testing machines where it can be fixed and calibrated without re-setting for longer time periods.


Fixed Focus 3D DIC optical measuring system is a robust and comprehensible pre-calibrated system for advanced stereoscopic strain analysis. Similar to Stereo ONE, the FIX device suits any static and quasi-static experiments with advanced requirements including out-of-plane deformations and motion measurements.

The FF3DDIC system offers high reliability for various applications like:

  • Tensile / Compression / Biaxial extensometers and inspection points.

  • Virtual strain gauges as a full contactless replacement of physical sensors.

  • Full-field analyses to identify the strain distribution and critical locations.
