Optical probes

For spectroscopic analysis methods in the chemicals and pharmaceuticals industries

In many fields of application in optical sensor and analysis technology, optical fibers and components are required for illumination and for light detection. We create customer-specific assemblies for various fiber types and fiber bundles that continue to function reliably under the harshest of conditions, such as in industrial environments – or even in outer space. Examples for the deployment of fiber optical components in a wide range of application scenarios include:

measuring probes in the chemicals industry
fiber feedthroughs for signal transmission in vacuum applications
fiber systems for temperature measurement in high-temperature applications
offshore measurement systems in wind turbines or on oil platforms
fiber measurement system in astrophysics
