OBELAB is introducing a new portable functional Near-Infrared Spectroscopy (fNIRS) system : NIRSIT Lite! 

It is a light-weight, easily configurable, multi-channel fNIRS neuroimaging system for prefrontal cortex, specifically targeted for research on children.

NIRSIT Lite is designed to measure variations in cerebral hemodynamics on a realtime basis by radiating a near-infrared light beam, at two wavelengths of 780nm and 850nm of LED, into the cerebral cortex.

Boasting light weight of only 180g, it is designed to fit the head sizes of children from preschool to high school.

The system comes with its dedicated monitoring and analysis software for researchers. 

Flexible design to fit various head sizes.
