The peripheral consists of two devices: the wireless light gun itself, called the "Transmitter", and a "Receiver" that connects to the second controller port of the Super NES console.
On the end is the infrared receiver lens, approximately 1 inch (25 mm) in diameter, which picks up the light from a TV.
The end of the eyepiece is very simple: it is a cylinder with the diameter of a quarter, with a removable rubber piece through which the shooter looks.
On the front is an oval-shaped black area, receding back from the two sides to an infra-red transmitter about the size of a dime.
At the end of the frame, the game software can retrieve this stored position to determine where on the screen the gun was aimed.
Most licensed Super Scope games include a calibration mode to account for both electrical delays and maladjustment of the gunsight.
