Description
Compact FTIR for operation with a fiber output and input
The Arcoptix FTIR-FC (Fiber-Coupling) is a variant of the FTIR Rocket spectrometer especially designed for operation with mid-IR optical fiber probes. It is a plug-and-play instrument including an IR source, high-stability interferometer, IR detector and SMA fiber couplers. The instrument is especially developed with process-monitoring applications in mind, using for example fibered ATR probes.
The Arcoptix FTIR-FC can be equipped with both 4-stage thermo-electrically (TE) cooled or liquid-nitrogen cooled MCT detectors. The TE-cooled detectors in the FTIR-FC are the most sensitive TE-cooled detectors availabe on the market and offer a reliable and maintenance-free operation. For ultimate sensitivity levels, the FTIR-FC can also be equipped with a liquid-nitrogen cooled detector. The 4-TE and liquid-nitrogen cooled detectors are intercheangable by the user.
- Ideal for operation with fibered ATR probes
- All-in-one solution: source, interferometer, detector and fiber-couplers
- Most compact fiber-coupled FT-IR on the market
- Available with TE-cooled or liquid-nitrogen cooled MCT detectors
Chemical process-control with fibered ATR probes
The Arcoptix FTIR-FC was developed with chemical process-control applications in mind, using ATR fibered probes. These probes can be immersed into highly corrosive liquids at high temperatures and pressures, making them suitable for use in chemical reaction vessels and other extremely harsh environments. A list of available probes can be found under the Accessories tab.

Free GUI basic software
The FTIR Rocket is delivered with a free graphical user interface (GUI) program.
The free basic software package allows the user to:
- Configure hardware measurement parameters (aplifier gain, averaging, …)
- Display real-time spectral measurement results
- Set reference spectra (white, dark) and choose among raw spectra, transmission or reflection mode
- Usual features such as save, open, zoom, rescale…
- Some specific features related to Fourier transform spectrometry: choose among spectrum or interferogram averaging, apodization, look and save the interferograms, etc.
