Abstract
A rotatable, bakeable vacuum sealed mount for an optical element, suitable for use on an endbell assembly for a gas discharge tube or as an integral part of a gas discharge tube for an ion laser comprises an elongated support member, having an axis and a passage along the axis of the support member. A first end of the support member is connected by a vacuum tight seal to the vacuum sealed chamber of the gas discharge tube, so that the passage has an opening toward the vacuum sealed chamber. A second end of the support member is connectable by vacuum tight seal to the optic, so that the second end of the passage has an opening toward the optic. A portion of the support member has a yield strength allowing adjustment by twisting of the support member about the axis for establishing a rotational alignment of the optic without breaking the vacuum of the vacuum sealed chamber. A bearing member, having a cylindrical bearing surface coaxial with the axis of the support member, supports the support member near the second end, so that the optic remains substantially transversely aligned relative to the axis of the support member during twisting for establishing the rotational alignment.
