UNIT FOR ADJUSTING LENS POSITION OF OPTICAL SYSTEM

摘要

PURPOSE: A position control unit of an optical system lens is provided to finely adjust the location of the optical system lens is to a shaft direction while controlling the generation of displacement of remaining direction except for the shaft direction. CONSTITUTION: The inside of a housing(40) is empty. A monolithic flexure hinge structure(10) is accepted in the housing while the top is fixed to the housing. The monolithic flexure hinge structure forms a lens mounting unit for mounting a lens at the lower side. A control ring is screwed in the inner side of the housing. A ring-shaped spring(30) is fixed and combined with the lower side of the monolithic flexure hinge structure. A flange unit is formed at the upper side of the monolithic flexure hinge structure to a radial direction.
