Abstract
An aperture mechanism includes at least one blade moveable along a path between a closed position and at least one open position. At least one hard stop is moveable between a first position, out of the blade path, and a second position in the blade path to position the blade in the open position when an edge of the blade contacts the hard stop. The hard stop is located out of a plane of movement of the blade when the hard stop is in the first position to simplify and make more accurate the positioning of the blade in the open position.
