  • High powered dual LEDs 32mW maximum illumination / optional next generation APD detectors with down to 33 pW sensitivity.
  • Proprietary automated ultra-fast source and detector specific signal optimization.
  • Variable tension spring holders offering optimal scalp coupling and comfort.
  • Full array short-distance detectors available.
  • Probe-level 9-axis accelerometer(s).

Signal quality is assured by our high-powered dual-tipped LEDs in combination with our variable tension Spring holders offering optimal scalp coupling along with our high performance SiPD or next generation APD detectors. Provisions for addressing extracerebral sources of confound include literature-recommended 8mm short-distance detectors with full array/head placement, as well as probe-level 9-axis accelerometry.

  • Specialized solutions for various applications and modalities; EEG, VR, TMS, MRI, VR etc.
  • Lightweight & compact form factor ~900 grams.
  • Wireless connection and onboard storage for tetherless recordings.

The NIRSport2 has been designed as a research platform from the ground up, yet with motion and movement in mind. Integration solutions are provided. Sporting a small form factor (162 mm x 125 mm x 60 mm) and weighing in at just 900 grams, it offers considerable versatility in motion-based applications. Furthermore fixation and integration solutions are provided for those applications involving other modalities, such as EEG, VR, and MRI*.


Aurora fNIRS Recording Software

The NIRSport2 comes together with Aurora fNIRS: our innovative software platform designed to maximize user-friendliness, flexibility and intuitive workflow.

In just a few clicks, Aurora fNIRS allows you to set-up a complete experimental configuration. The automated signal optimization algorithm ensures optimal signal quality before a measurement is started. Once data is being recorded, HbO and Hb concentration changes can be visualized in real-time in several display modes. In addition, high-end whole-head visualizations are immediately available.

Aurora fNIRS is developed exclusively for the NIRx NIRSport2. Learn more about Aurora fNIRS.

Turbo Satori Real-Time fNIRS Analysis Software
The NIRSport2 platform is fully integrated with Turbo-Satori for real-time online analysis within neuro-feedback and BCI applications. For more details, please see here

Satori – Powerful and Easy to use fNIRS Analysis Software
Satori natively reads the data recorded with the NIRSport2 and Aurora. Satori includes the current standard fNIRS processing methods and statistical tools. For more details, please see here

NIRSport2 Extensions

Concurrent Physiological Measurements with NIRxWINGS

The NIRxWINGS module for peripheral physiology measurements extends the NIRSport2. You can collect pulse oximetry (PPG), heart-rate variability (HRV), oxygen saturation (SpO2), respiration, temperature, galvanic skin response (GSR), and bipolar signals such as EMG and ECG. All signals fully synchronized and in one data stream.

NIRxBorealis translating fMRI to fNIRS

NIRxBorealis couples up to two NIRSport2 devices with optical fiber-based optodes for fNIRS data acquisition in an MRI environment. The primary advantage of this system is the flexibility to use the very same NIRSport2 platform for both mobile and MRI-integrated experiments. NIRxBorealis offers ability for low profile fibers for transcranial magnetic stimulation (TMS).
