The Brite MKIV is a state-of-the-art, wearable, and flexible multi-channel fNIRS device designed for advanced brain oxygenation research. Weighing just 300 grams, this ultra-light system can be easily attached to the Artinis fNIRS headcap, offering unmatched portability and comfort for diverse participants, including children and elderly individuals. Combined with offline data storage, the Brite is ideal for studies in any environment—labs, clinics, or even outdoors.
Equipped with advanced multi-wavelength light transmitters, the Brite MKIV provides continuous, real-time data seamlessly integrated into our user-friendly analysis software. Its innovative multi-power gain control includes four power levels and auto-power settings, ensuring optimal data quality across various skin tones, hair types, ages, and cortical distances. Including sensors with high sensitivity, setup is now easier and quicker, especially when measuring over hair.
