Abstract: A shutter for an optical system, such as a small infrared camera, for alternately blocking and exposing an optical sensor to light includes an electrically conductive coil, having a center long axis, a magnet element rotatably mounted within the coil with an axis of rotation perpendicular to the center long axis of the coil, a shutter flag element connected to the magnet element, and a shutter base element supporting the shutter flag, magnet, and coil. Energizing the coil in a first manner causes the rotatable magnet to rotate from a first position to a second position and energizing the coil in a second manner returns the magnet to the first position, causing the flag to alternately block and expose the optical sensor.
