From Concept to Market Readiness – Precision That Makes the Difference.
The engineering competence of FOS Inon Fiber Optics is the foundation for innovative and marketable products in medical technology and photonics.
Holistic Engineering for Medical Technology and Photonic Systems
The engineering expertise of FOS Inon Fiber Optics serves as the catalyst for market-oriented innovations in photonics and medical technology. We do not view engineering as a standalone service, but as a continuous development process—from the initial idea and feasibility studies to the transition to series production.
Our interdisciplinary team of physicists, optics designers, electronics developers, and design engineers operates at the interface of light and technology. We develop optical systems with the highest precision—whether for analytical procedures, surgical applications, or biomedical diagnostics.
What Sets Us Apart:
Photonics Engineering with a System-Level Understanding
We design and simulate complex optical beam paths—from free-space laser modules to fiber-coupled light sources. In doing so, we rely on precise optics designs, integrate optoelectronic components, and consider both thermal and mechanical boundary conditions.
Product Development for Medical Devices
Our experience in engineering for medical technology encompasses diagnostic, therapeutic, and surgical systems—always with a focus on regulatory requirements (e.g., MDR), functional safety, and user-friendliness.
Optomechanics Meets CAD Design
Mechanical precision is the backbone of functional photonics. Our design engineers create opto-mechanical mounts, heat sinks, adjustment units, and housing solutions—utilizing modern CAD software and always optimized for manufacturing.
Laser Components & System Integration
We develop custom-specific laser modules, collimators, fiber couplers, or filter assemblies—always tailored to your application. Our know-how in photonics system integration ensures that mechanics, optics, electronics, and software merge into a robust overall system.
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.
