Light-induced reactions
Photo-induced and -catalyzed reactions play a key role in a wide range of applications from clean energy (CO2 reduction) to physiology (protein dynamics, Vitamin D synthesis).
Mid-infrared spectroscopy is well suited for studying these processes due to the high sensitivity and specificity without labeling. When the starting time of the reaction is well defined, e.g. by a short light pulse, the reactions can be well resolved by difference spectroscopy.
Achieving high signal-to-noise ratios at short time scales from microseconds to sub-second is key. Yet this is not achieved with regular FTIR spectroscopy, due to the limited brightness of the globar light source as well as the time required for mechanical movement of the interferometer mirror.
The IRis-F1 spectrometer allows the observation of a chemical band with microsecond time resolution with high signal quality due to the high brightness of the broadband laser source and the simultaneous detection of all laser modes.
The underlying technique of dual-comb spectroscopy is increasingly successful in a range of applications. For the first time, it is made available as an integrated turn-key system by IRsweep.

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.
