The fNIRS phantom is a BioPixS novel product specifically designed for fNIRS device developers and manufacturers
Introducing the fNIRS Phantom (Functional Near Infrared Spectroscopy Phantom) – a breakthrough innovation meticulously crafted by ISO/IEC experts to empower developers of fNIRS devices. It has been developed within the group “IEC/TC 62/SC 62D/JWG5” which involves the major world experts of functional Near Infrared Spectroscopy and aims at defining the characteristics of a functional phantom meant to be used in the framework of the standard IEC 80601-2-71. Indeed, our fNIRS Phantom is designed to meet the stringent requirements of the standard IEC 80601-2-71 and its future upgrade.
Why choose the fNIRS phantom
- Standard Compliance: Align your fNIRS device development with the international standard effortlessly. Our fNIRS Phantom caters to the specific tests mandated
by the IEC 80601-2-71 standard, ensuring that your device adheres to established benchmarks.
- Optical Attenuation: Designed as a diffuse attenuator, our phantom is constructed from a long lasting stable polymer scattering material. It guarantees
a minimum optical loss of 40 dB for each wavelength of use, in perfect accordance with the standard’s specifications, in particular for implementing the tests 201.12.1.101.5 “PATHLENGTH-DEPENDENT HAEMOGLOBIN CHANGE” and 201.12.1.101.6 “Signal Stability”.
- Integrated Dual Aperture Slider: The sliding mechanism boasts two apertures with different diameters, enabling the switching of optical loss by 3 dB to
4 dB when required. This precise adjustment ensures that your device can detect even the subtlest changes in optical properties as required in the Test 201.12.1.101.5 “PATHLENGTH-DEPENDENT HAEMOGLOBIN CHANGE”.
- High Optical Loss for specific tests: For critical assessments such as the “Signal-to-Noise Ratio” (Test 201.12.1.101.8), our phantom steps up. With an optional
add-on, it delivers a remarkable optical loss of at least 60 dB for every wavelength within the 600-900 nm range, enabling low signal measurements.
- Modular Design: The fNIRS Phantom comprises two distinct parts separated by the slide mechanism. Sized at minimum 60x60x20 mm and 60x60x10 mm as required by
standard, these components fit seamlessly into the phantom box, which measures 70x70x44 mm overall.
- Changeable adaptors: While the standard configuration includes a C-mount for input and output, we offer a range of optional adaptors to accommodate various optodes and fiber termination types, including SMA and FC/PC.

WHAT IS fNIRS
Functional Near Infrared Spectroscopy (fNIRS) is a groundbreaking non-invasive imaging technique that offers a window into the inner workings of the human brain. Developed as an extension of the well-established principle of near-infrared spectroscopy (NIRS), fNIRS goes a step further by allowing researchers and clinicians to monitor real-time changes in hemoglobin concentration in the brain, shedding light on neuronal activity patterns.
At its core, fNIRS relies on the inherent properties of near-infrared light, which can penetrate biological tissues, including the human skull, to a certain depth. When near-infrared light is emitted into the brain and then detected after passing through various layers of tissue, it undergoes subtle changes in intensity due to the absorption of light by oxygenated and deoxygenated hemoglobin. These changes in light intensity are meticulously analyzed to provide valuable insights into brain activity, making fNIRS a powerful tool for neuroimaging.
The applications of fNIRS span a wide range of disciplines, including neuroscience, psychology, clinical research, and brain-computer interfacing. Researchers leverage fNIRS to study cognitive processes, brain development, mental disorders, and even human-computer interaction, all without the need for ionizing radiation or intrusive procedures.
In this exciting field, precision and adherence to standards are paramount. The fNIRS Phantom is the essential companion, meticulously designed to ensure your fNIRS device adheres to international standards and benchmarks. Together, fNIRS and the fNIRS Phantom open doors to a world of possibilities in neuroscience, cognitive science, and beyond.
