FiPOS ATR Fiber Probes

FiPOS product line


FiPOS product line from Ostec & art photonics GmbH is a cluster of innovative fiber optic probes and fiber probe couplers designed for in-line analytical analysis in a wide spectral range from UV to Mid-IR (550 cmˉ¹ to 55 550 cmˉ¹).


FiPOS family of immersion fiber probes includes ATR, transmission, transflection, fluorescent, and diffuse reflection probes all compatible with any FT-MIR, FT-NIR or dispersion spectrometer, process-photometer, IR-LED, or QCL spectral sensor to use in-line for PAT applications.


FiPOS Fiber Probe Couplers (FPC) couple any FTIR spectrometer with various fiber optic probes and upgrade it to eliminate sampling and to run reaction monitoring in-line. Our fiber probe couplers provide high coupling efficiency for ATR – absorption, transmission, or reflection process-spectroscopy in a wide spectral range from UV to Mid-IR to use fiber-coupled FTIR not only with LN-cooled MCT detectors but with TE-cooled MCT and uncooled IR detectors as well.

  • 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
  • Unique developments in the field of high temperature fiber optic ATR probes (up to +250ºС)
  • Unique high-quality IR optical fibers
  • Reduced losses between fibers and ATR crystal tip

  • Customized solutions


FiPOS probes design is cleanable for many processes where probe optics can be contaminated by media. Industrial probes are compatible with process interfaces SensoGate-FOS and Ceramat-FOS with approved fittings to secure their semi or full automated use in complete process control systems. They can be retracted, cleaned, and calibrated during chemical process to enable remote process-control in any liquid, gas, or solid mixtures under harsh environmental conditions.


Combined with FTIR spectrophotometers, our fiber probes facilitate qualitative and quantitative product analysis and enable the determination of specific chemical and physical properties.


We offer two categories of FiPOS product portfolio: standard and customized.


The standard products consist of pre-configured probes and probe couplers, which can be implemented in the laboratory, pilot plants, or in production.


The customized products allow users to custom configure fiber probes and couplers based on their unique process requirements.


Choosing right ATR fiber probe


IROS 05 + FiPOS probes

The most important issue in the FTIR analysis is right choice of type of the ATR fiber probe. The best probe type depends on the nature of the sample and environment conditions.


Regardless of the fiber probe, the concept is still the same – light from the FTIR analyzer is guided by the optical fiber probe onto the sample. From there the light with the sample spectra is captured by a fiber optic detection line and returned to the analyzer where the data is analyzed.


Beam tracing is very simple – the radiation goes from the input fiber to the ATR crystal, is reflected (once or several times) from the ATR tip surface, and focuses back to the output fiber coupled to the spectrometer detector.


Partial penetration of IR-light in media of ATR-tip contains its absorption spectra.


The ATR crystal is reliably fixed inside metal or polymer parts of the tip, sealed with polymer ring and can not fall away.

ATR probe scheme

General design of FiPOS ATR fiber optic probes


ATR probe consists of: ATR crystal tip at the end of immersible part (so-called shaft) and Mid-IR optical fiber bifurcated to 2 legs with SMA connectors.


ATR crystal tip and Mid-IR optical fiber are the most important parts of the probe.


Probes with a metal shaft and robust stainless steel protective conduit are suitable for reaction monitoring in the plant and in a lab reactor.


Probes with polymer shaft and replaceable ATR tips are suitable for lab applications.
