Abstract
The invention relates to an electromagnetically actuated microshutter comprising: a moveable plate that can rotate about an axis, connected to a stationary frame by two arms aligned on both sides of the plate to said axis, and comprising on its periphery a conductive loop; and below the assembly formed by the stationary frame and the moveable plate, a group of magnets having distinct magnetic orientations, arranged in such a manner so as to create, in regard to the moveable plate, a lateral magnetic field, in the plane of the frame, oblique in relation to the axis of rotation.
