Revolutionizing Wine Fermentation Monitoring with Fiber-Based Spectroscopy

By Stanislav Perevoschikov

Ever wondered how you can monitor wine fermentation in real time without disturbing the process? In our latest application note at art photonics, we explain how the combination of mid-infrared (mid-ir) and uv-vis spectroscopy with fiber-based technology is transforming fermentation analysis. Our study on Federweißer (fresh wine) revealed that key ethanol peaks become clearly visible […]

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.
