Automatic Brightness Control (ABC)

An electronic feature that automatically reduces voltages to the micro-channel plate to keep the image intensifier’s brightness within optimal limits and protect the tube.

The effect of this can be seen when rapidly changing from low-light to high-light conditions; the image gets brighter and then, after a momentary delay, suddenly dims to a constant level.
