Abstract:
An electromechanical shutter device comprising a base member and a shutter assembly comprising: an electrical current source member; a shutter member movable between a light beam blocked position and a light beam passed position; a light beam blocking member associated with the shutter member; a shutter coil associated with the shutter member which generates an electromagnetic force when energized; at least one magnet which generates a magnet flux directed towards and intersecting the shutter coil; electrically conductive means connecting the electrical current source member to the shutter member for passing electrical current to energize the shutter coil and to control movement of the shutter member between the light beam blocked and passed positions; wherein when the shutter coil is energized, an electromagnetic force is generated that interacts with the magnetic flux to thereby cause movement of the shutter member between the light beam blocked and light beam passed positions.
