In an embodiment, a driving device includes a base, a lower spring, a lens unit, an upper spring, a coil, and a magnet. The base has a terminal. The lower spring is elastically provided between the base and the lens unit. The lens unit is movably provided on the base relative to the base. The upper spring is provided on the lens unit. The coil is provided on the lens unit. The magnet is arranged corresponding to the coil. One end of the terminal is exposed from a bottom portion of the base, and the other end extends toward the upper spring to be electrically connected to the upper spring.

An electro-mechanical device includes a payload of a magnet affixed to a mirror, and a coil assembly. The coil assembly has a body with wound electrically conducting wires and a payload aperture through which the payload travels. When voltage is applied to the coil assembly, current through the coil assembly generates a magnetic field resulting in a net upward force on the magnet that accelerates the payload to travel upward through the payload aperture for the mirror to block an optical pulse. As the magnet travels through the payload aperture, due to a magnetization direction of the magnet and a magnetic field in an upper portion of the coil assembly, the magnet experiences a net deceleration force that arrests the payload.
