The VFS200 is a visual flash stimulator for electroretinogram (ERG) on small animals that emits high power pulsed light using a xenon bulb. The user can precisely control the pulse duration and power of the xenon flash using one knob and a display. The unit is controllable using a standard 0-5V TTL signal. The VFS200 can be used with our Ganzfeld VUS200.
