Fiber Optic ATR-Probes

Main features:

  • High throughput in any part of Near & Mid InfraRed-spectrum
  • ATR-tip shaped for immersion in liquid flow without dead zone
  • Flexible and robust for industrial applications in harsh environment
  • Compatible with all spectrometers and automated process-interfaces

FlexiSpec® product line from art photonics is the latest generation of Attenuated Total Reflection. Near & Mid IR-fiber ATR-Probes produced for any type of FT-NIR, FT-IR and other IR-spectrometers, photometers and IR-LED or QCL spectral sensors. ATR immersion fiber optic probes with patented design are suitable for reaction monitoring in lab, pilot plant and for full automated process control.
