A mount for an optical element is disclosed in which an optical element can be adjusted to a plurality of positions to change the position of an output beam. In order to provide a mount which can be adjusted to precisely position the output beam in orthogonal directions, the optical element is mounted in a holder which is rotatable about a first axis, and the holder is mounted on a support which is rotatable about a second axis. When the optical element is rotated about the first axis, the output beam is adjusted along an arc in an X direction; and when the support with the holder thereon is rotated about the second axis, the output beam is adjusted along an arc in a Y direction.
