Industry- and Application-Oriented Solutions
Your Success in Focus – with Precision, Know-how, and a Genuine Passion for Photonics
FOS Inon Fiber Optics represent more than mere component manufacturing. We provide sophisticated, integrated solutions—tailored to the demanding requirements of the medical technology and photonics industries.
Our approach is application-oriented and interdisciplinary: from feasibility studies and prototyping to series production, we collaborate with our clients as partners, maintaining a keen eye for detail. In doing so, we integrate optics, mechanics, and electronics into intelligent, functionally verified units.
Medical Technology: Accelerating the Path from Concept to Market-Ready Product
The development of medical devices is a complex undertaking that necessitates a partner intimately familiar with both regulatory and physical requirements. We support you through every phase:
- Rapid Prototyping for Medical Devices to facilitate swift design evaluation and the early integration of clinically relevant feedback loops.
- OEM Manufacturing of Medical Systems: from individual components to complete optical assemblies—for start-ups and established manufacturers alike.
- Production Support for optics, light sources, and opto-mechanical units.
Our precision manufacturing delivers reproducible quality with the requisite flexibility to shorten innovation cycles.
Photonics: Component Manufacturing with a System-Level Understanding
In photonics, every micrometer (µm) is critical. Consequently, we develop and manufacture high-precision optical and mechanical components for deployment in sophisticated photonic systems:
- Lens mounts, mirror mounts, and opto-mechanical assemblies engineered to stringent tolerances.
- System manufacturing for laser technology—from thermally robust support structures to actively aligned subsystems.
- Optics Engineering: design, simulation, and testing of optical setups—directly coupled with our manufacturing capabilities.
Our engineering team thinks in terms of wavelengths, tolerance chains, and finesse values. This is precisely why we can deliver solutions that excel in real-world photonic applications—whether in research, industry, or medical technology.
Manufacturing Process
To ensure our light guides and fiber optic products meet the highest standards, we rely on a specialized manufacturing process. This allows us to guarantee exceptional chemical and tactile robustness so they can perform optimally in their respective environments. Precision is a critical factor in this, true to our motto: “Making the impossible happen.”
Materials Used
- Borosilicate: Glass with high temperature resistance and chemical resilience.
- PMMA (Polymethylmethacrylate): A thermoplastic, lightweight plastic with high light transmittance.
- Silica-Hard Clad: A robust plastic coating for improved strength and durability.
- Silica-Silica for UV and NIR Wavelengths: Our specialized glass fibers, optimized for the transmission of light in the ultraviolet (UV) and near-infrared (NIR) ranges.
PMMA is a thermoplastic material, known under brand names such as Plexiglas or acrylic glass. In fiber optics, PMMA is used for:
- Flexible, cost-effective fiber optic cables are used
- Large core diameters (up to several millimeters)
- Applications using visible light
PMMA fibers are less temperature-resistant than glass fibers (max. 70-100°C), but significantly more flexible and less expensive. This makes them a particularly good choice for lighting or sensors where extreme temperatures are not present.

Borosilicate (also called “boron glass”) is a special type of glass with a high boron oxide content. It is the same material used to make heat-resistant laboratory glassware and baking molds. In fiber optics, it offers:
- Excellent chemical resistance to acids and alkalis
- Good temperature resistance up to approximately 400-500°C
- Low thermal expansion (less stress during temperature changes)
Ideal for standard industrial applications and lighting.

Optional Specifications:
- Various apertures available
- Polarization can be maintained
- Anti-reflection coating possible
- Various lengths, diameters, bending radii, converters, and vacuum feedthroughs optional
- Various connectors and ferrules suitable for industry and medicine
SMA (Sub-Miniature A) is a standard screw-type connector for fiber optic cables, designed for laboratory equipment and spectrometers. The connector has a 1/4″-36 thread. FSMA is the fiber optic version with a specially protected ferrule for the sensitive fiber end face. Standardized connectors allow you to connect our cables directly to your equipment, or we can manufacture custom connectors for your specific application.

Silica-silica fibers consist entirely of high-purity quartz glass (silicon dioxide), both the core and the cladding. This construction offers:
- Extremely high temperature resistance up to 1000°C
- Optimal transmission in the UV range (below 300 nm)
- Excellent transmission in the NIR range (1000-2500 nm)
- Minimal absorption losses
Therefore, these fibers are primarily used in high-performance lasers, UV curing, and spectroscopy.
