Multiplexer for multi-channel operation

One spectrometer – many measurement points 

Polytec multiplexers expand the capabilities of NIR spectrometers by enabling sequential measurements at several points with just one device. Using an optical switch, multiple probes can be connected and addressed one after another. This makes multi-channel operation efficient and cost-effective, while ensuring reliable process monitoring across different stages of production.
