How to Measure ATR Spectra Directly in Solution with Fiber Optic Probes

Moving Beyond the Bench: In-Line FTIR Monitoring with ATR Probes For decades, Attenuated Total Reflection (ATR) has been a standard technique for FTIR spectroscopy. However, most users are restricted to standard ATR inserts or benchtop accessories. While effective for static lab samples, these setups introduce a critical bottleneck: the sample must be extracted from the […]

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.​
