Optical beam precision positioner

Claim 1

A laser relay mounting assembly which receives and conducts an incident laser beam to a laser beam relay which produces therefrom a laser output, said laser relay mounting assembly adjusting said laser output coincident with a desired axis, said laser relay mounting assembly comprising: a laser beam relay; a frame, upon which said laser beam relay is mounted; a spherical pivot which is mounted on said frame and which receives and directs said incident laser beam to said laser beam relay; a mirror mounted on said frame; a relay mounting trunnion which holds said laser beam relay so that it is between and colinear with said spherical pivot and said mirror; a first positioning mechanism which has a base that attaches said relay mounting trunnion to said frame, said first positioning mechanism tilting and translating said laser relay into a position such that said mirror reflects said laser output so that it is coincident with said desired axis by adjusting said output laser's angle of incidence as it reaches said mirror; a mirror mounting trunnion which holds said mirror so that it is colinear with said spherical pivot and said laser beam relay; and a second positioning mechanism which has a base that attaches said mirror mounting trunnion to said frame, said second positioning mechanism being able to translate and rotate said mirror mounting trunnion in three dimensions with respect to said frame, said second positioning mechanism thereby tilting and translating said mirror into a position such that it reflects said laser output so that it is coincident with said desired axis.
