Abstract
There is provided an improved tool for use in aligning both angular and translational position of a laser beam at a rotating joint of a laser beam delivery system having one or more rotatable laser optics. The tool includes a tool chassis which receives a laser beam directed along a laser beam axis to the rotating joint of the delivery system and the tool chassis. The tool further includes structure for mounting the tool chassis on the rotatable part of a rotating joint of a laser beam delivery system to be aligned, a position monitor for monitoring the laser beam received relative to a two dimensional coordinate system during rotation of the tool, and a laser beam focusing lens which focuses at least a portion of the laser beam received such that translational deviations of the received beam are eliminated from that focused portion of the beam. In conjunction with the position monitor, angular orientation of the received laser beam can be isolated and monitored when passed through the focusing lens, and translational position of the received beam can be monitored when not focused by the focusing lens.
