Abstract

The invention provides a laser beam expanding lens transposition mechanism, and relates to a transposition mechanism in the optics apparatus technology field. The laser beam expanding lens transposition mechanism comprises a work bench, a linear platform pedestal, a leading screw, a guide rail, a sliding stand, a laser beam expanding lens, a bearing, a shaft coupling, a stepping motor, a linear displacement sensor and the like. The bearing is installed on the linear platform pedestal, the leading screw is filled into the bearing, and the linear platform pedestal is installed on a workbench. An output shaft of the stepping motor forms coaxial connection with the leading screw through the shaft coupling, the leading screw traverses a screw hole of the sliding stand, a lower surface of the sliding stand slidingly contacts an upper surface of the guide rail, a base plate of the laser beam expanding lens is fixed on the sliding stand, and the laser beam expanding lens makes rectilinear movement with the sliding stand. A connection bracket joint is fixed on a side surface of the sliding stand, an expansion end of the linear displacement sensor connects with the connection bracket joint, the laser beam expanding lens makes rectilinear movement with the sliding stand, and the linear displacement sensor records a position of the laser beam expanding lens.

Description

Technical field [0001] The invention belongs to a laser beam expander transposition mechanism involved in the technical field of optical instruments. Background technique [0002] The laser beam expander is used to change the divergence angle of the laser beam. In order to obtain different laser divergence angles, multiple laser beam expanders are installed in some laser optical paths. When a large laser divergence angle is required, a certain laser beam expander will be used. Moving out of the optical path, when a small laser divergence angle is required, a certain laser beam expander will be moved into the optical path. The existing technology closest to the present invention is the laser beam expander developed by the Changchun Institute of Optics, Fine Mechanics and Physics, Chinese Academy of Sciences Transposition mechanism, such as figure 1 As shown, it includes a workbench 1, a laser beam expander 2, a conical pin 3, a screw 4, and a beam expander foot 5. [0003] Adjust t...
