<p>A laser alignment system (10) comprises a body (12) housing a laser system emitting three laser beams (14a, 14b and 14c); and a mounting (16) to which the body (12) is connected. The mounting (16) comprises a course alignment adjustment mechanism (18) allowing the body (12) to be moved about a point (20), and a fine alignment adjustment mechanism (22) for adjusting the position of the point (20). The course alignment adjustment mechanism (18) is in the form of a ball (24) and a clamp (34) that can selectively clamp and release the ball (24). The fine alignment adjustment mechanism (22) comprises three threaded shafts (66) that can be screwed along their respective longitudinal axis to move the position of the point (20).</p> |
