mirSense is committed to developing and making cutting-edge laser technologies available to everyone on a daily basis. From protecting people to protecting their environment, they build tools that allow everyone to breathe cleaner air, to move safely and to live in good health.

Quantum cascade lasers are an advanced technology, resulting from the conquest of space, precise at the atomic scale.

Passionate about the immense possibilities offered by these lasers, they build sustainable, smarter and more accessible products every day. Today mirSense offers efficient and precise solutions, powerful and robust, deployable widely and easily.

MIRCHIP X is a OEM on-line gas sensor for industrial applications, specifically designed to meet the expectations of integrators, gas system manufacturers, and gas analyzer manufacturers. The module is based on photoacoustic spectroscopy, using mirSense’s patented Quantum Cascade Laser (mid-IR wavelengths).

Targeted molecules are illuminated by a Quantum Cascade Laser at a specific wavelength – one laser per molecule – allowing them to absorn laser energy according to Beer-Lambert’s law. The gases will then expand and compress, creating a sound wave that is easily picked up with a microphone. Leveraging its expertise in QCL design and photoacoustic detection, mirSense has designed a versatile and robust gas sensor capable of reaching sub-ppm level within a few seconds. MIRCHIP X is suitable for a wide range of applications, such as air quality monitoring, process control, healthcare…

CalibSun delivers best-in-class solar irradiance and power production forecasts to help solar producers, traders and aggregators boost trading profits and cut imbalance costs.

CalibSun provides a solar forecasting suite integrating on-site data, covering all operational time horizons. INSTANT delivers 1-minute nowcasts using a network of sky imagers and on-site sensors, while NEXT produces deterministic and probabilistic intraday and day-ahead forecasts by combining real-time on-site data with NWP models and satellite imagery. They were ranked #1 in three independent 2025 benchmarks across 1.5GW of European and Asian PV assets.

iUMTEK is a French Deeptech and Cleantech startup specializing in industrial instrumentation for real-time elemental chemical analysis. Founded in 2017 and originating from the technology transfer program of the CEA (French Alternative Energies and Atomic Energy Commission), the company develops measurement solutions based on photonics combined with AI.

Thanks to these technologies, iUMTEK’s instruments can instantly identify and quantify all elements of the periodic table in solids, liquids, or gases, without any sample preparation or extraction. This enables instantaneous, non-invasive analysis that can be directly integrated into industrial environments.

One of the company’s flagship products is the TX 4000 analyzer, an autonomous and modular instrument capable of delivering real-time measurements for diagnostics, quality control, traceability, and industrial process optimization. iUMTEK also offers feasibility studies, on-demand analysis services, installation support, operational training, and maintenance.
