Applications

Test and Measurement Technology

Miniaturized precision

fionec’s miniaturized measuring probes are especially suitable for demanding applications in the micro and precision manufacturing sector. With diameters starting from just 50 µm, they allow for fast, contactless scanning of fine surface microstructures and the smallest of cavities. The fiber optic measurement sensors are used in our FDM Series distance measuring systems, among others.

Applications

Detecting surface roughness and waviness e.g.in micro-drilled holes, on precision optics, on small gears
Inspection of geometric and position tolerances (GD&T)
Highly accurate distance and position detection
Measurement of expansion, drift and vibrations
Measurement of freeform surfaces in scanning mode for 3D modelling

Data and signal transmission

Bundled innovation

Industry 4.0, the gigabit society and modern research need one thing above all else: high-performance glass-fiber infrastructure for fast and reliable data communication. fionec develops innovative custom fiber optic solutions and prototypes for state-of-the-art applications in the telecommunications and life sciences sectors.
