MedelOpt Infinity Systems


Powerful, Flexible Neuroscientific Research Systems for fNIRS+EEG

whole-head high-density EEG+fNIRS
Part #: INFIN 16-32-EEG, INFIN 16-16-EEG, INFIN 16-16

MedelOpt® Infinity systems provide high-density NIRS with EEG for very high density whole brain mapping and custom advanced montages with variable depths. The flexible, adaptable headset allows acquisition for up to 8 hours. MedelOpt adjusts to real-world situations or Virtual Reality environments with a specific design to fit any head mounted VR display. Use for research applications with regions of interest from prefrontal to the cerebellum and through parietal, and lateral cortex. Integrate MedelOpt with other physiological data from BIOPAC devices for multimodal data acquisition.


MedelOpt Systems are designed to support a range of settings and can be expanded as needed.

  • EEG up to 512 Hz and/or fNIRS up to 64 Hz
  • fNIRS density ranging from High Density to Very High Density
  • Emitters/detectors can be added to the headset to increase channel count

16/16 128 theoretical channels
16/32 252 theoretical channels

Unique design developed by researchers for researchers delivers bimodality to flexi-modularity. MedelOpt systems can be adapted from EEG/fNIRS modality to hyperscanning to support a range of interests and budgets. See MedelOpt Mobility Systems for high density mapping with complete mobility with an unlimited range of acquisition. See MedelOpt Tandem Systems for synchronized acquisitions, hyperscanning, and social interactions. Add a Mobility Pack (MiniPC + Battery + USB cable) to increase the mobility range and protocol options for your experiment.
