ABSTRACT:
A lens device includes: a housing formed with a module-mounting hole that has a hole axis, and provided with a mounting surface that is disposed radially and outwardly of the module-mounting hole; a lens module having a lens axis; and an alignment correction unit for mounting the lens module on the housing at the module-mounting hole. The alignment correction unit includes a module barrel coupled to the lens module, an elastically deformable component clamped by the module barrel toward the mounting surface of the housing, and a set of screw fasteners for fastening the module barrel onto the mounting surface at angularly spaced apart locations relative to the hole axis. Depths of threaded engagement of the screw fasteners with the mounting surface are independently adjustable to permit adjustment of the lens axis of the lens module relative to the hole axis of the module-mounting hole.
