Abstract:
A laser level device comprising:a reference surface;a laser beam generator mounted to said reference surface;a compensator supported proximate to said reference surface, said compensator including a pendulum having a polygonal body with at least a four point suspension, an optical device mounted to said polygonal body in the path of a laser beam produced by said laser beam generator to redirect said laser beam in a perpendicular direction and to further redirect said laser beam for compensating for any tilting of said laser level device, and a keeper mounted to said reference surface and at least partially surrounding said polygonal body such that an air gap is provided between said polygonal body and said keeper for affording rotational and lateral damping;a lens mounted to said reference surface between said laser beam generator and said optical device of said compensator for collimating said laser beam; anda beam sweeper supported above said reference surface in the path of said redirected laser beam from said optical device to sweep the redirected laser beam in a plane.
