The portability of LIGHTNIRS allows visualizing brain function activity in real-time in a more natural state than other methods. Consequently, it is being used in a wide range of applications including medical research, developmental psychology, education, cognitive science and engineering.



With its compact size, the LIGHTNIRS easily fits inside a specially designed backpack, providing a comfortable fit for a variety of tasks. The inbuilt lithium-ion battery enables the operation of the LIGHTNIRS for up to four hours before recharging is required. This combination of battery power and portability provides researchers enhanced flexibility, allowing them to bring the instrument to various locations for measurements or to have subjects wear it during real-life activities requiring more mobility. This contrasts with conventional MRI, which requires individuals to be constrained inside a scanner during measurement acquisition.

LIGHTNIRS incorporates safe, yet powerful, class 1 three-wavelength semiconductor lasers and photodiode detectors to provide superior signal quality and sensitivity that ensures the highest signal quality while maintaining the portability features. An advanced integrated probe design enables a unique mounting of the fibre optic and optode holder device to facilitate a sensitive connection to the head. A flexible fibre arrangement allows users to easily adjust the setup for effective measurement of any brain region of interest. Additionally, specially-designed holders or caps enable application-specific measurements including cognitive neuroscience research, motor measurements, as well as medical and rehabilitation research.



System Features

  • High measurement freedom due to its lightweight and compact design. 
  • Three wavelengths are used to measure variations in the concentration of Oxygenated, deoxygenated and total hemoglobin, which are used as indicators for brain activity.
  • Real-time monitoring process functions during acquisition.
