Technical Note: Choosing the Right Optical Fiber for Your Process Spectrometer

Is your process spectrometer giving you the full picture? For engineers working in process control and Process Analytical Technology (PAT), the quality and reliability of real-time data are paramount. While the spectrometer itself is the core of the system, its performance often hinges on a component that can be easily overlooked: the optical fiber. The […]

Webinar: Combi Probes - Solving the "Blind Spot" of Single-Mode Spectroscopy

In complex chemical analysis and biomedical diagnostics, relying on a single spectroscopic technique often results in a "blind spot." While Near-Infrared (NIR) offers speed, it frequently lacks specificity. Raman spectroscopy provides a precise molecular fingerprint but often battles fluorescence interference. Mid-IR offers excellent structural detail but is limited by shallow penetration depths. The Challenge: Spatial […]

PIR fiber full circle production

Full manufacturing cycle of polycrystalline fibers in Berlin​

art photonics has implemented a full production cycle for PIR (polycrystalline infrared) fibers. The process begins with the controlled preparation and homogenization of halide salts, ensuring precise stoichiometry and purity. These raw materials undergo thermal synthesis to form the polycrystalline structure, followed by extrusion under high pressure to create preforms. The preforms are then subjected to fiber drawing using advanced extrusion and stretching techniques, allowing us to produce fibers with a wide range of diameters (from 300µm to 1000µm) and optimized optical properties. Core/Clad PIR fibers are transparent over a broad spectral range 3 – 17 μm.​

One of the key characteristics of PIR fibers is their low optical loss without absorption peaks across the specified spectral range. For CO₂ laser cable production, art photonics applies a proprietary SMART end-face processing technology to suppress Fresnel reflection and maximize transmission efficiency.​

The PIR fibers are used for high-performance optical cables and probes, designed and manufactured in-house at art photonics for applications in spectroscopy, thermal sensing, and industrial process monitoring.​
