The Vielight Neuro Alpha is a transcranial-intranasal NIR (near infrared) headset, a complete upgrade from the original Neuro. It includes updated microchip LED boosting technology and improved transcranial clusters, providing three times the power density over older versions with a refined form to fit a larger variety of head sizes and shapes.
The Vielight engineering team uses microchip technology in the intranasal diode to provide one of the largest amounts of power from a near infrared pulsed LED source.
Near-infrared light is nearly invisible to the naked eye, making the beam appear much dimmer than it actually is. The power density of the intranasal LED is 25 mW/cm2. The power density of the transcranial LED is 100 mW/cm2 per diode.
