Measures oxy-, deoxy- and total hemoglobin in
a non-invasive and truly portable way.



The OctaMon is ideal for capturing brain activity while having the freedom to perform daily activities including exercise. The device consists of 8 channels covering the full prefrontal cortex. Like the PortaLite, the OctaMon measures changes in oxygenation in terms of oxyhemoglobin, deoxyhemoglobin and total hemoglobin. This device can be applied in a variety of dynamic settings as often required in neuroscience and sports science research.


  • Non-invasively
  • In the lab and in the field
  • Continuously
  • Affordable
  • Without the need for special infrastructure
  • Without specially trained personnel

Why the OctaMon?

This NIRS device is unique in it's kind. Other similar 8-channel NIRS systems are often non-portable, heavy, expansive, complicated and take a long time to set-up. Coming from the research field ourselves we wanted to change that. With the OctaMon we focussed on the usability and portability of NIRS while still providing the same quality of data as measured by large NIRS systems. The OctaMon is a lightweight and plug and play device with no set-up time. It works with multichannel LED's, giving you continuous and real-time feedback in our data analysis software that is delivered with the system. 

The Octamon research package makes monitoring oxygenation easy and accessible. Hyperscanning (monitoring multiple subjects at the same time) is also possible with the OctaMon, while our software provides you to combine different NIRS devices within one data stream. 
The subjects are even enabled to perform physical activities like walking or running, while the device is connected with bluetooth (up to 100 meters) to the laptop. 

NIRS applications

The OctaMon is ideally suited to investigate cognitive functions, especially during dual tasking (for example combined with driving or walking). The prefrontal brain regions is in particular studied in working memory or attention tasks, but is also of particular interest for studying neuropathological disorders such as Alzheimer’s disease or ADHD. This is because of its strong interconnection with deeper brain regions, such as the Basal Ganglia. The headband covers a large area of the brain so it could also be used for detecting epileptic seizures. As the OctaMon is a really lightweight and comfortable device it can be used where subjects hardly notice they are being monitoring.

Would you like more than 1 NIRS device? You can measure with multiple (different) Artinis NIRS devices at the same time. All data is synchronised and stored in one datafile. We also offer NIRS EEG packages.


All of our NIRS devices can be combined with the PortaSync. It is a handheld device for synchronisation of the different types of instrumentation and the data files they produce.

Artinis NIRS products are intended to be used for research applications only. Our products are not sold as Medical Device as defined in EU directive 93/42/EEC. Our products are not designed or intended to be used for diagnosis or treatment of disease.
