IRsweep
Swiss company
IRsweep is a Swiss company offering optical spectroscopy solutions and multipass absorption cells.
The spectroscopy is based on semiconductor quantum cascade laser frequency combs
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.
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
IRsweep was founded in 2014 as a spin-off from the Swiss Federal Institute of Technology (ETH Zurich). 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.

Why this record matters
“IRsweep” is worth following because a concise public description often conceals a longer documentary argument. Here, IRsweep, Swiss and company provides the most credible route into that argument.
The record creator and administrative purpose are central evidence, because official documentation reflects both action and institutional priorities. The source revision retrieved here is dated Aug 16, 2026. The linked authority identifier is Q25058077. Authority coordinates are 47.409, 8.509. 3 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 2014 and 2021.
Later summaries often reconcile disputed chronology or motive more neatly than the contemporary record permits. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
