Technology
IRsweep develops optical sensing solutions in the mid-infrared range – the fingerprint region of most molecules. The technology is based on frequency comb quantum cascade lasers (QCLs), offering broad spectral coverage and high measurement speed in combination with high brightness.
This provides advantages in fields such as biospectroscopy, catalysis, combustion diagnostics, reaction monitoring, and more. The main advantage compared to conventional spectroscopic solutions is high spectral and time resolution which enables in situ analysis of sub-second reactions.

Understanding the noise of a measurement
Signal to noise is an important topic when discussing the performance of a spectrometer and a convenient way to describe this is through Allan deviation, which provides a way to quantify the noise present in a system as a function of integration time. … Continue reading
Unique Features
Large spectral coverage
The system relies on lasers emitting several hundred colors at the same time, allowing to probe the sample at different wavelengths simultaneously.
The bandwidth is typically >60 cm-1 for a dual-comb source. To expand the coverage beyond that, the dual-comb source in the IRis-F1 spectrometer can be exchanged by the user without tools in less than 5 minutes and little to no realignment.
The dual-comb modules are available with center wavelengths ranging from 900 cm-1 (11 µm wavelength) to 2200 cm-1 (4.5 µm wavelength) and can be added to existing systems.
High brightness
Frequency combs are high brightness light sources which enable applications that are not feasible using thermal sources.
For example, transmission measurements become possible for samples which are currently only accessible with reflection measurements.
Additionally, thicker samples can be used, which substantially simplifies sample preparation and avoids clogging in the sample flow. The high brightness and heterodyne detection can also be exploited for stand-off detection applications.
Fast detection
The acquisition of a spectrum is accomplished in less than one µs. Signal quality can be improved by integration of the signal over longer times.
Microsecond-scale kinetics are accessible as well as millisecond to second scale reaction monitoring at high signal-to-noise ratios, even at large absorptions.
High spectral resolution
The system’s resolution is less than 0.001 cm-1, ultimately limited only by the linewidth of the laser line and not the sampling technique, as is the case in FTIRs.
The decoupling of resolution and sampling is described in more detail in a technical note.
IRsweep’s robust and scalable technology allows you tomeasure faster, find lower concentrations and distinguish substances better than with current spectroscopy solutions.
