Patent ID: 7242540

Claim:
An axis-adjustable optical device comprising: a base having a mounting surface, said mounting surface extending in first and second directions that are perpendicular to each other; a first adjustment unit including a support seat, at least one first biasing component disposed between said support seat and said mounting surface of said base, and a plurality of first screw fasteners each extending in a third direction perpendicular to the first and second directions for coupling said support seat to said base; a second adjustment unit including a holding seat and a pivot seat that are coupled to said support seat and that are spaced apart from each other in the first direction, and a guide hoop that is coupled to said pivot seat and that is pivotable relative to said pivot seat about the first direction; and a lens unit including a barrel that extends in the first direction, that defines an optical axis, and that has a first segment and a second segment extending from said first segment, said first segment having a universal coupling relation with said holding seat of said second adjustment unit, said second segment having said guide hoop sleeved thereon; wherein pivotal movement of said guide hoop relative to said pivot seat drives movement of said barrel such that the optical axis is adjusted in the second and third directions.
