ABSTRACT:
An axis-adjustable optical device includes: a base; a first adjustment unit including a biasing component disposed between a support seat and the base, and a plurality of screw fasteners for coupling the support seat to the base; a second adjustment unit including a guide hoop coupled and pivotable relative to a pivot seat on the support seat; and a lens unit including a barrel that defines an optical axis, and that has a first segment having a universal coupling relation with a holding seat on the support seat, and a second segment having the guide hoop sleeved thereon. Pivotal movement of the guide hoop relative to the pivot seat drives movement of the barrel to adjust the optical axis.
