Vibrational stark spectroscopy
Anyone interested in the influence of applied external electric fields on optical spectra of proteins, biological systems, or electrode interfaces, has probably dealt with long measurement times when using IR spectroscopy. These often limit studies to high concentrations of analyte and make systematic parameter sweeps (e.g. of pH) infeasible. Moreover, dielectric breakdown may occur after long measurements.
The IRis-F1 dual-comb spectrometer offers acquisition times which are 100 times shorter than FTIRs at similar signal-to-noise ratios, making smaller analyte concentrations and parameter sweeps accessible. The increased brightness also enables thicker samples, additionally boosting signal strength.
The IRis-F1 achieves this performance by employing dual-comb spectroscopy, with mid-IR broadband frequency comb lasers as light sources. They offer brightness orders of magnitude higher than thermal light sources found in FTIRs – and the multi-heterodyne detection scheme operates without 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.
