Formation and characterization of macromolecules
Polymers are used as plastics, paints, elastomers, dental compounds, composites and more, giving them a wide range of applications. The polymerization process is typically monitored with infrared spectroscopy.
The IRis-F1 spectrometer offers high signal-to-noise ratios at time resolutions from microseconds to seconds. It can be used to monitor the polymerization and help understand polymer formation and stabilization, as well as unwanted processes such as cross-linking, aging, contamination or decomposition. Due to its high time resolution, intermediates can be resolved as well.
Typical sample interfaces such as ATR can still be used. In addition, the sensitivity can be increased compared to FTIR-based systems, by increasing the sample interaction length.
The IRis-F1 achieves its superior performance by employing dual-comb spectroscopy based on broadband lasers. The lasers are detected in a so-called multi-heterodyne regime – the acquisition time is not restricted by moving parts.

IRis-C
The IRis-C is the next generation instrument in IRsweep’s quantum cascade laser frequency comb spectrometer line. It uses the same dual-comb spectroscopy technology as IRsweep’s IRis-F1, offering microsecond time-resolution, high spectral resolution, and high optical brightness in the mid-infrared. With a substantial reduction in physical dimensions and price, it is easily adaptable to any type of application and fits even tighter budgets.
IRis-F1
The IRis-F1 spectrometer offers you an unmatched combination of speed, brightness and multi-color measurements. The quantum cascade laser frequency comb spectrometer is the first turn-key frequency comb spectroscopy system. As opposed to single-frequency operation, which necessitates tuning over your spectral range of interest, you will achieve a broad spectral coverage in a single-shot measurement.
IRis-core
The IRis-core is an ideal basis for the setup of such a system in the mid-IR range: It offers two overlapping free-running QCL-based frequency comb lasers in a single system. The system outputs already co-aligned beams and comes with a set of drive instructions with factory-characterized heterodyning conditions. The system comes complete with drive electronics and a control computer with a graphical user interface.
