NEWS RELEASE
IRsweep Introduces IRspectrometer — Industry's First Turn‐Key
Dual‐Comb Mid‐IR Spectrometer — Unmatched combination of
speed, bandwidth, and brightness opens new possibilities for
analysis in applications —
SAN FRANCISCO/Photonics West 2017 — Jan. 28, 2017 — IRSweep today introduced
IRspectrometer — the first commercial table‐top frequency comb spectrometer offering
microsecond time resolution combined with a large spectral bandwidth and high spectral resolution.
The introduction of IRspectrometer advances spectroscopy in a variety applications, including the
analysis of biological samples, monitoring of fast reactions, and chemical composition analysis.
IRspectrometer excels where fast time resolution or high throughput and superior brightness is
required — including applications involving a complex background matrix or where multiple similar
molecules must be simultaneously quantified.
Advancing Mid‐IR Spectrometry
IRspectrometer is the first instrument to provide the advantages of dual‐comb spectroscopy in a
complete turn‐key solution. Featuring the radically different approach of dual‐comb spectroscopy
that was awarded the Nobel Prize in Physics in 2005, IRspectrometer overcomes the limitations of
the well‐known trade‐offs of speed, resolution, and signal‐to‐noise ratio of Michelson FT‐IRs.
Unique features of IRspectrometer include:
‐ High speed: The fast time resolution of IRspectrometer (as low as 1 μs for a full spectrum)
enables monitoring fast processes and high‐throughput applications without relying on
techniques like step‐scan in FT‐IRs.
‐ Superior brightness: The brightness of IRspectrometer’s laser frequency comb source is
superior to conventional globar‐based systems — providing an extraordinary dynamic range
and enabling the analysis of high‐absorption samples. This advantage significantly eases
sample preparation for liquid and solid analytes.
‐ Bandwidth: IRspectrometer delivers microsecond resolution at high bandwidths. Center
wavelengths between 6 µm (1700 cm‐1) and 9.5 µm (1050 cm‐1), covering fundamental
amid absorption bands, are available. The range between 5 µm (2000 cm‐1) and 12 um (830
cm‐1) is under development.
‐ Signal‐to‐noise: IRspectrometer achieves signal‐to‐noise ratios above 1000 per data point
within less than a millisecond.

New Possibilities for Analysis
IRspectrometer’s unmatched combination of speed, bandwidth, and brightness opens new
possibilities for analysis in key applications. Examples include:
‐ Time‐resolved bio‐spectroscopy: IRspectrometer’s fast time resolution enables the
observation of conformal changes in proteins in microseconds. The instrument’s brightness
allows measurements of higher absorption samples than with FT‐IRs.
‐ High‐throughput IR analysis: When optimizing the activity of enzymes through modifications,
IRspectrometer’s high‐throughput rates excel in the analysis of large sample sizes.
‐ Chemical composition in the analysis of gaseous, liquid and solid samples: IRspectrometer’s
superior brightness can handle high‐absorptions samples. The instrument’s high resolution
can resolve even narrow spectral features.
Immediate Availability
IRspectrometer is immediately available as a tabletop instrument with a standard sample interface in
transmission configuration. For more information, see live demonstrations of IRspectrometer at BiOS

Company background Zurich, 18.01.2017
IRsweep’s vision is to revolutionize optical sensing by introducing an ultrafast laser spectrometer in
the mid‐infrared. It is based on Quantum Cascade Laser Frequency Combs invented by IRsweep Co‐
founders in 2012 at ETH Zurich. The spectrometer is the backbone of IRsweep’s commercial activities
in the next few years and represent the technological basis for further integration into process
analytics and possibly portable applications.
The problem
A spectrometer is a common piece of equipment in industrial and laboratories. Its main use is to
investigate the molecular composition of a sample in a non‐destructive way. The main drawback of
today’s spectrometers is their low speed: measurement times of seconds to minutes are needed for
the acquisition of a complete spectrum. However, many processes happen on time‐scales of
microseconds, which can’t be observed with these techniques. Moreover, the analysis of large sample
numbers take long.
The solution: the IRspectrometer
The IRspectrometer is a laser‐based infrared spectrometer which exploits the extraordinary sensing
performance of so‐called frequency‐combs in the mid‐infrared spectral region. As a result, the
IRspectrometer offers an unmatched combination of high measurement speed (microsecond time
resolution) with the high brightness of a laser‐based instrument and a high spectral bandwidth.
The high measurement speed of the IRspectrometer opens new possibilities. For example, researchers
can observe the folding or conformational changes of proteins in real‐time. By this, they can learn
about correct and incorrect protein folding states. With this knowledge, they can find the reason for
protein folding errors and eventually cure diseases such as Alzheimer or Parkinson. The spectrometer
will moreover enable high throughput screening and the brightness of the laser source enables analysis
of strongly absorbing samples.
Target market
Global demand for analysis has been ever increasing and is roughly segmented into a laboratory and
process analytical instruments. The former is further segmented into three main segments: molecular
analysis (optical methods and mass spectrometry), separation analysis (chromatographic methods)
followed by different methods of detection and atomic analysis. Innovation in the segments concerns
performance (speed, resolution) and efficiency (throughput, ease of use, maintenance).
In this context, IRsweep initially focuses on the laboratory instrument market, because it is more
performance driven than cost driven and because it is easier to access for new technologies. In own
market research, several fields with a push for performance (e.g. speed, brightness) were analyzed in
24 customer interviews. Most promising is the field of time‐resolved spectroscopy of biological
molecules, where there is a large research community in Europe as well as the US. Furthermore, the
Page 2
research community proliferates into the important pharmaceutical industry sector with further
growth opportunities.
Team
The management and founding team unifies three complementary key members. Dr. Andreas Hugi
developed the core laser technology of IRsweep. The worldwide leading role of ETH Zurich and IRsweep
and the first technology demonstration is due to his persistence and vision. Sensing system
competence is provided by Dr. Markus Mangold. He is experienced in developing portable optical
sensor systems based on laser technology. His latest development is a shoe‐box‐size sensor system
that is installed on a running tram for continuous air pollution measurements. Dr. Markus Geiser
unifies the necessary technical competences with experience in the financial sector. Before finishing
his PhD in Physics at ETH Zürich, he studied physics in Harvard and at TU Munich. He also worked for
the private equity fund Auctus Capital Partners in Munich before.
Competition
The laboratory analytical instrumentation market is dominated by large players such as Thermo Fisher,
Agilent and Bruker offering products based on established methods. In this market, mid‐IR sensing is
a young, developing field which is being developed mostly by start‐up companies. However, larger
players, such as ABB and Emerson have shown interest as of late with acquisitions of companies
specialized in mid‐IR sensing, posing also a possible exit strategy.

IRcell – long path in a compact designKeeping track of trace gas levels is of critical importance in a wide range of applications. For low abundance trace gases, small ab-sorptions can be observed by increasing the optical path length. This is achieved using multi pass cells.With the IRcell, we offer a multi pass cell consisting of only a single, circular mirror. The cell body is at the same time the mirror reflecting the optical beam.The advantage of such a configuration lies in its robustness towards mechanical stress such as vibrations or temperature changes. With this design, we offer an optical path of 3.5 m.
Unique features
Sub-permille optical noise: Very low optical fringe levels <0.2‰ rms are specified for the IRcell. Typical values are closer to 0.1‰ asseen in the figure. The fringe level further reduces drastically at de-creased spectral resolution.
Compact design: A 2-dimensional beam-pattern enables low sample volume. Patented absorption mask shown in black.
High Optical throughput:IRcell provides improved performance by combining high optical throughput with an enhanced path-to-volume ratio.
