Olythe is a French deeptech company specialized in breath gas analysis for road safety and public health.

We develop a patented miniaturized infrared spectroscopy (NDIR) technology enabling fast, reliable, and non-invasive detection and quantification of substances directly from exhaled breath.

🚓 Our flagship device, OCIN₂O, is the first portable analyzer dedicated to nitrous oxide (N₂O) detection in breath, addressing a growing road safety challenge.

🔬 Already validated and industrialized, our technology paves the way for multi-substance detection (alcohol, N₂O…) from a single breath sample.
