ColorBurst

The ColorBurst is the hand-held mini-Ganzfeld stimulator of the Espion system. It produces a uniform field of light which is presented to the subject monocularly. The color and intensity of the light are precisely controlled in real time to create a range of visual stimuli, including flashes, flickers onset/offset and steady backgrounds. The ColorBurst fully supports all ISCEV Standard Ganzfeld tests. Two ColorBursts may also be combined to form a dual binocular stimulator with the addition of a dual controller box.
