IRsweep is a Swiss company offering optical spectroscopy solutions and multipass absorption cells.

The spectroscopy is based on semiconductor quantum cascade laser frequency combs[1][2] in the mid-infrared wavelength range. The company is based in Zurich, Switzerland and was founded in 2014 and acquired by Sensirion Holding in May 2021.[3]

The technology is used for high speed absorption measurements of different molecules and is robust against cross-sensitivities. Such sensor systems are in high demand for process analytics as well as research applications, as the mid-infrared range hosts the strongest absorption features of many molecules.

History

[edit]

IRsweep was founded in 2014 as a spin-off from the Swiss Federal Institute of Technology (ETH Zurich).[4] The company commercialized its first product after having developed its prototypes for academic research projects. The first derived product is the IRcell, a cylindrical multipass cell combining a long optical path in a small detection volume.
