Ecto Goggles are designed to allow the wearer to see invisible ghosts and visually track P.K.E. valences. A camera function was later added to take photographs related to ectoplasmic activity. They also have infrared and Night Vision capabilities.

On the right side of the Ecto Goggles are a set of buttons, including a red one and a black one, that operates the camera and prints the photograph. The flash unit pops up, the photograph is taken, and then the photograph prints out the left side.

an eyepatch-like monocle version of the Goggles, called Ecto Monocle was also created and used by Egon Spengler.
