<p>A mount for an optical element is disclosed in which an optical element (121) 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 (121) is mounted in a holder (120) which is rotatable about a first axis (Z'), and the holder (120) is mounted on a support (116) which is rotatable about a second axis (Z). When the optical element (121) is rotated about the first axis (Z'), the output beam is adjusted along an arc in an X direction; and when the support (116) with the holder (120) thereon is rotated about the second axis (Z), the output beam is adjusted along an arc in a Y direction.</p> |
