Therefore, the accuracy of its posture directly affects the quality of the output beam. This article discusses the design of the device. It is mainly divided into 3 parts. The bending mechanism uses constant external force to elastically bend the optical elements to obtain the required surface shape. The cooling mechanism is used to reduce the thermal deformation of the mirror surface, thus reducing the surface error of the mirror. The overall mechanical system provides 5-DOF attitude adjustment. Based on this, this design adopts a combination scheme of a four-bar bender with independent bending moment, the copper blades inserted in the GaIn eutectic filled trough solution and 5-DOF attitude adjustment of multi-layer granite. Through a series of calculations, simulations and tests, it is demonstrated that the design indexes meet the requirements, thus verifying the feasibility of the scheme.
