Fiber Probe Coupler: FPC-6M

The FlexiSpec® fiber probe couplers from art photonics GmbH allows easy coupling of fiber probes with any FTIR spectrometer. Coupling of FlexiSpec® probes with FT-spectrometers eliminates the necessity to prepare samples and put them into the sample chamber, and makes remote analysis possible for molecular reaction monitoring in-line.

The FPC-6M is the newest generation fiber probe coupler for large FTIR-spectrometers based on six mirror design providing the maximum coupling efficiency with a variety of fiber probes. It can be installed in sample chamber of a number of different FTIR spectrometers from Thermo Fisher: iS10, iS50, Nicolet 6700, and Nexus 670.

The FPC-6M can be tailored to match iBox and other industrial or lab FTIR- spectrometers, coupling probes with SMA or other connectors.


  • Efficient coupling of fiber probe to FTIR-spectrometer
  • Compatible with sample chamber of iS5 and other FTIR
  • In/Out ports compatible with SMA-terminated fiber probes
  • Mirror optics to enable operation in wide spectral range
  • Pre-aligned for distinct FTIR-model and adjustable to maximize coupling efficiency


  • Upgradable for a variety of FTIR-models and adjustable for high coupling efficiency
  • Upgrading Lab FTIR to replace sampling for remote reaction monitoring in-line
  • Easy to install in sample chamber - as any other accessories
  • Process-control with robust fiber probe terminated by SMA or other connectors
