About Swisens
Swisens AG, based in Emmen (canton of Lucerne, Switzerland), develops, produces and distributes instruments and solutions for real-time measurement and monitoring of aerosol particles. The systems detect bioaerosols, pollutants and other solid particles for industry and science. Core products are the aerosol particle measurement systems SwisensPoleno Mars and SwisensPoleno Jupiter as well as the SwisensAtomizer for generating stable dust and aerosol atmospheres. The measurement combines digital holography, UV-induced fluorescence spectroscopy and scattered-light and polarization measurement with two laser wavelengths; integrated machine-learning algorithms identify the particles automatically. The portfolio is complemented by the SwisensEcosystem for pollen and bioaerosol monitoring as well as services covering training, maintenance, data management and enhancement of the identification algorithms. Customers include organizations from environmental monitoring, research, air quality control, public health and occupational safety; reference customers are MeteoSwiss, the University of Manchester, Sciensano, the Finnish Meteorological Institute and Suva.

Technologies & Measurement Methods
Digital Holography
Delivers high-resolution in-flight particle images for determining morphology, even in the lower micrometer range.
UV-induced Fluorescence Spectroscopy
Captures spectrally resolved fluorescence intensity and lifetime to determine the biochemical composition of the particles.
Scattered-Light and Polarization Measurement
Time-resolved measurement with two laser wavelengths provides information on size, surface structure and refractive index.
Machine Learning / Artificial Intelligence
Integrated algorithms identify particles based on captured morphological and chemical properties.
Open-Source Software (Python, GPL)
Customers can adapt software components themselves, from raw data acquisition to the operation of ML models.
