R&D

NEO Monitors’ Innovative R&D
Following developments and trends in the world of science, having early access to new technologies, and cultivate relationships with key research institutes allows us to maintain a global leadership in gas spectroscopy. Currently we act as an industrial partner and system integrator in five European research projects. These are targeting the development of new laser-sources for a variety of spectral regions, as well as new detection schemes. This auspicious combination will open up new and exciting possibilities in gas sensing that will allow us to release new, revolutionary products in the future.
Detection of gases in the mid-infrared (MIR) spectral region
Nowadays laser-based gas spectrometers in the near-infrared (NIR, 760 nm to 2300 nm) have been accepted by industrial users as the best available technology for a number of different applications. However, for some gases specifically of interest for emission and process control it is necessary to move into the mid-infrared region (MIR, 3 µm – 12 µm). This is either because the gas of interest (e.g. sulfur dioxide, SO2) has no absorption features or, in case of nitric oxide (NO) and nitrogen dioxide (NO2), the absorption strength and thus the sensitivity is too low in the NIR.
The figure below shows as an example of the absorption strength of NO. As can be seen, the absorption strength in the MIR (around 5.2µm) is about 1000 times stronger than in the NIR (around 1.8µm). Therefore, NEO Monitors has set one focus of its R&D on the investigation of MIR laser sources to be able to utilize the stronger absorption and thus increasing the sensitivity of its sensors.
Ongoing projects


The sensors will be demonstrated and validated with two real-time in-line pilot installations regarding bread, tortilla and cheese production.

The SAFESENS project will address the direct societal need for more reliable and earlier fire detection in combination with accurate occupancy detection. SAFESENS aims at achieving this goal with the co-integration of gas sensor and presence detection technologies, which should enable an enhanced safety and security of buildings, its occupants and safety workers.

Recent projects

The mid-infrared (MIR) spectral region is emerging as the preferred wavelength region for a number of applications including free space communications, absorption spectroscopy, chemical and biological sensing and LIDAR applications. The key elements for the different applications are the optical source and the detector.

These novel high performance photonic sources will allow the development of the following highly sensitive detection systems:
- Laser based sensor for remote detection of alcohol against drunk driving
- Laser based sensor for formaldehyde monitoring
- Laser based sensor for hydrocarbon leak detection (NEOs commitment)
