Optical 3D measurement technology for high point density and accuracy in all phases of production

Optical measurement technology in use

We offer optical 3D scanners based structured-light projection technology for highly accurate and automated part inspection. The FLEX-3A product line is designed for the incoming goods department, toolmaking, initial sampling and release, as well as for automated inspection during production.

The high-resolution scan data is capable of being compared directly against a CAD model, or used for dimensional, shape, and positional tolerance measurements. With object point resolutions down to 5 um, as well as our smart multi-image referencing using virtual targets, the FLEX-3A is ideally suited for high-precision automated 3D inspection of complex small parts.

Optical 3D scanner for automated inspection

The 3D scanners of the FLEX-3A series are suitable for first sample and prototype inspection, as well as automated random sample inspection during production.

complete system flex 3a


The FLEX-3A utilizes a closed housing concept, that when combined with complete automated data acquisition, calculation and evaluation, helps ensures long-term stable system calibration and operation under production conditions.

The use of an object fixed reference camera enables highly accurate and automated photogrammetric combination of partial views into one complete 3D model, with no need for registration targets.

Two integrated motorized axes by standard can be supplemented by additional axes and motion sequences as necessary.
