Abstract
A mechanism for reducing radial offset in a collimnated optical beam associated with an angled end fiber and minimizing an angular offset caused by collimator lens centration errors is presented. An angled end fiber is oriented in a supporting collimator so that the angled surface of the fiber is parallel to the collimator axis, thereby compensating for the radial offset. The angled end fiber is again so oriented after the angular-offset producing collimator lens rotation (used to determine the optical center of the lens) and the collimator lens is moved in a direction parallel to the collimator axis to provide a desired output focal position for the lens.
