General straightening simulation device for optical system

A general straightening simulation device for an optical system relates to the technical field of optical instrument clamps. The device comprises a base, a guide rail, a large lens frame, a detector support and a lens support. The guide rails are bilaterally symmetrically fixed on the top surface of the base, the large lens frame is fixed in the middle of the foremost end of the base, the lens support is composed of a sliding seat, a first three-dimensional fine adjustment frame and a small lens frame, the first three-dimensional fine adjustment frame is fixed on the sliding seat, the small lens frame is installed on the front side of the first three-dimensional fine adjustment frame through a rotating mechanism, and the sliding seat is installed on the guide rails in a sliding mode; the detector support is composed of a fixing plate, a second three-dimensional fine adjustment frame and a frame plate, the second three-dimensional fine adjustment frame is fixed to the fixing plate, the frame plate is installed
