Optical measurement - accurate to the µm, reproducible, non-contact.

In-line optical measurement – to ensure that all dimensions are correct!

High quality and complex parts consist of many high precision manufactured and assembled single components. Every single component must satisfy narrow dimensional tolerances for trouble-free, error-free functioning. Systems for precise optical 2D and 3D measurement are required for verifying compliance with these narrow tolerances. Depending on the production process and concrete requirement, the off-line measurement for correct setting of the processing machines or the in-line measurement of every part or combinations of the two methods could be the right solution. Octum has been supplying the right solution for µm accurate, reproducible optical 2D and 3D measurement for both applications for many years. Our system solutions achieve the necessary measuring equipment stability (repeatability & reproducibility). 

The image processing solutions for 2D optical measurement are designed application-specific and usually contain bi-telecentric lenses incident light or telecentric back -light illumination. In addition to careful planning and selection of the right optical components, the mechanical structure with highly accurate adjustments of the components is very important. Octum provides practice-proven mechanics and wobble units from its own production for this. Together with the mature system software, we achieve repetitive accuracies of up to 2 µm according to method 1 in our projects. Depending on the task, smart cameras or PC-based image processing systems with actually up to 29 MP cameras can be used.

The image processing solutions for 3D optical measurement usually contain 3D triangulation cameras or stereo cameras. Here too, the careful planning of the components and implementation is decisive for the achievable measuring accuracies. We implement 3D optical measurement exclusively with PC-based systems.

Typical implemented measuring tasks are:

  • Measurement of piston rings (impact clearance, jaw width, light gap, axial height, diameter…)
  • Measurement of metal hard disk housings and plastic housings
  • Measurement of compressor wheels and sealing rings
  • Measurement of plug pins incl. wobble circuit
  • Measurement of gear wheels, bearings, con rods, multilayer seals, engine blocks
  • Measurement of plastic cups and lids
  • Measurement of syringes and vials
  • Measurement of pharmaceutics labels and wound materials etc.
