ABSTRACT:
An optical beam precision positioner assembly is disclosed. This assembly permits the optics of a laser beam relay to be positioned and secured coincident with the gimbal axis of the laser beam pointing system. An incident laser ray enters the precision positioning system through the midpoint of a spherical pivot, continues to a mirror surface, and the reflected ray exits the system so as to be coincident with a specified axis. The positioner has the capability to translate and/or rotate on three axes to locate the mirror surface at the exact position required to produce a reflected ray coincident to the desired axis. Positioner adjustments are made by rotating screws and back lash in the adjustment screws is eliminated through the use of compression springs. Locking screws located in the positioner secure the alignment.
