Mirsense's team at work on laser

Our company

laser is smart.

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, we 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.

We rely on the know-how of competent and creative women and men, passionate about their profession, anxious to put excellence, rigor and innovation at the service of all

We are located in France, at the heart of internationally renowned research, production and innovation ecosystems. Our world needs technologies we can all trust. This is our commitment to everyone.


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

By developing and producing our own lasers, supported by patents and exclusive techniques, we offer professionals miniaturized modules allowing them to respond to new uses or strengthen their competitiveness, with an unprecedented quality-price ratio.


Our business sectors

mirSense mainly operates in two sectors : Defense & security and in Industry & environment

Industry and environment

Monitoring and diagnosis of air quality are essential for providing clean and safe air for breathing. The chemical industry, oil and gas industry, food and beverage industry, pharmaceutical industry, water treatment and power industries require new technologies to detect the main industrial gases or for monitoring chemical processes (such as scrubber process, gas leaks detection, gas production…). mirSense provides disruptive solutions with both lasers for spectroscopy and high-end gas analysers.
