Abstract
A device for transporting an optical element so that inclination of the optical element is substantially prevented to more precisely control the position of the optical element, including: a base; a transporting member that supports the optical element and is movably disposed along a predetermined direction with respect to the base; a magnet extending from the base along a movement direction of the transporting member; a coil that is coupled to the transporting member and generates a magnetic field when an electrical signal is applied thereto; and a magnetic substrate that is disposed on the transporting member and applies a force to the transporting member toward the magnet due an action of a magnetic force between the magnet and the magnetic substrate.
