Anwendungshinweis: Polymerklassifizierung mit NIR-Spektroskopie mit faseroptischen Sonden

By Stanislav Perevoschikov

Eine zuverlässige Identifizierung und Klassifizierung von Polymerrohstoffen ist für die Qualitätskontrolle und eine effiziente Verarbeitung unerlässlich. Wussten Sie, dass die Nahinfrarot-Spektroskopie (NIR) in Kombination mit modernen faseroptischen Sonden eine leistungsstarke Lösung bietet? Diese Technik ermöglicht eine schnelle, zerstörungsfreie Analyse außerhalb des Labors und macht es möglich, Messungen direkt vor Ort oder online durchzuführen. Die faseroptischen […]

Application Note: Polymer Classification with NIR Spectroscopy with Fiber-Optic Probes

By Stanislav Perevoschikov

Reliable identification and classification of raw polymer materials are essential for quality control and efficient processing. Did you know that near-infrared (NIR) spectroscopy combined with advanced fiber-optic probes offers a powerful solution? This technique allows for rapid, non-destructive analysis outside the lab, making it possible to perform measurements right in the field or directly online. […]

Description

Chalcogenide As-S glass fiber transmits IR-radiation in the spectral range of 1.1 – 6.5μm. High performance CIR core/clad fiber are drawn with core diameters span from 8µm to 340µm.

Advanced drawing process with double polymer jacket provides a superior mechanical strength and high flexibility of CIR- fibers.

Low optical losses and small absorption peaks over the mentioned spectral range ensure a successful use of CIR-fiber for a wide range of applications.
