OCIEngine & PRO

Miniaturized infrared spectroscopy sensors: A French know-how.
All of Olythe’s know-how is the result of years of research and development to develop OCIEngine, a compact and easy to integrate sensor using the most accurate and reliable NDIR technology.



Infrared Spectroscopy Technology mastery

Years of R&D have been invested in developing, mastering, adapting and miniaturizing infrared spectrometry technology. It results into a compact design that is easy to integrate. This technology provides ultra-reliable and accurate gas measurements.


OCIEngine PRO is an infrared spectrometer that measures Volatile Organic Compounds (VOC) in the air. It is specific to analyse a molecule of interest.


The measuring chamber of the sensor is crossed by infrared radiation. When the air is introduced into this chamber, the molecules of interest absorb a part of the radiation, which reduces the intensity of the optical signal. The concentration of the gas can therefore be deduced according to the Beer-Lambert’s physical law.

Our expertise:
breath analysis

The patented breath analysis system developed by Olythe guarantees precise and reliable results comparable to those obtained by law enforcement’s breathalyzers.

The exhaled air is sent into a measuring tank traversed by infrared radiation produced by the optical transmitter. Part of the radiation is absorbed by the molecules present in the tank enabling a precise calculation of the concentration.
