About FOS Inon Optics

FOS Inon Optics is a owner-managed, medium-sized manufacturer of custom fiber optic cables and fiber bundles headquartered in Niederschelden-Siegen. The company produces fibers with core diameters from 10 to 2400 µm, custom fiber optic assemblies, flexible light guides, fiber optic probes for flame monitoring, and PAT fiber optic sensors for inline spectroscopy. The portfolio is complemented by engineering services (optical design, simulation, optomechanical design), CNC parts, laser marking, technical 3D printing for prototypes, LED lighting solutions, as well as OEM manufacturing and rapid prototyping for medical devices. Customer industries include medical technology, analytics and spectroscopy, pharmaceuticals and biotechnology, process analytics, power plants and energy technology, aerospace, and laser and lighting applications. Production is carried out in accordance with ISO 9001:2015 at the Siegen and Aßlar sites; the company operates its own fiber manufacturing facility with a fiber drawing tower, preform oven (2000 °C), coating extruder and diameter measurement. Mechanical precision components are manufactured with eccentricity deviations below 15 µm.
