Olythe – Precision Breath Analysis for Public Safety

Olythe is a French technology company specialized in non-dispersive infrared (NDIR) spectroscopy for exhaled breath analysis. Founded in 2013 and based in Aix-en-Provence, Olythe develops compact, high-performance gas analyzers for applications in law enforcement, road safety, and health monitoring.

Our flagship innovation, OCIN₂O, is the first portable breath analyzer capable of detecting nitrous oxide (N₂O) — also known as “laughing gas” — directly in exhaled air. This disruptive technology offers a fast, non-invasive, and robust solution for field screening of N₂O misuse, particularly in the context of driving under the influence.
