Raman vs. Mid-IR ATR Spectroscopy for In-Line Reaction Monitoring: Technical Note

Mid-infrared (mid-IR) and Raman techniques are complementary vibrational spectroscopy methods utilized extensively in Process Analytical Technology (PAT). While both probe molecular vibrations, they rely on fundamentally different optical effects: mid-IR ATR detects the absorption of mid-IR radiation, whereas Raman relies on the inelastic scattering of visible or near-infrared (NIR) laser light. For system integration in […]

Precision by Design: What Quality Control Really Looks Like at art photonics

Every fiber, cable, and probe that leaves our Berlin facility gets put under a microscope. Literally. Before a product ships, we inspect the fiber end faces for cracks and contamination, check core/clad geometry, and verify transmission against spec. On mid-IR assemblies, that means confirming losses stay within 0.2–0.3 dB/m in the 9–13 µm range — […]

CPACT Webinar: Bridging the Gap from the Lab to Real-Time Process Control

Transitioning from offline sampling to real-time, in-line monitoring remains one of the most significant bottlenecks in Process Analytical Technology (PAT) today. When process engineers are forced to wait on delayed lab results, it impacts both efficiency and process optimization. To help address this challenge, art photonics is proud to announce an upcoming webinar hosted by […]

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.​
