Application Note: Air vs. Water: Finding the Optimal Reference for NIR Spectroscopy

The optimal choice of a spectral reference is important for building accurate calibration models. In our latest publication of Application Notes, art photonics explores the practical differences between using air and water as references in the quantitative analysis of liquid solutions. NIR-spectroscopy is widely used for quantitative analysis of solid and liquid samples. When measuring […]

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.​
