With the continuous development of the photoelectric technology, the distance of the object to be observed is more and more far, the integral resolution of the optical system is higher and higher, and the requirement of the reflector type is higher and higher. In an optical system, in order to correct an optical axis of the optical system, a normal direction position and a mirror surface angle of a mirror surface of a mirror part need to be adjusted, and after the adjustment, a phenomenon that a mirror base mounting surface and a base mounting surface are not coplanar (shown as unequal height or line contact, as shown in fig. 1) often occurs, so that the mirror part is mounted on the base, and the mirror base is fastened by a screw to deform, thereby causing the mirror surface to be poor in shape, and even the screw tightening force of the screw is different, the mirror surface is deformed differently. Once the position and the angle of the mirror surface of the reflector are adjusted, retesting the surface type of the mirror surface is mostly infeasible, so that the surface type of the reflector is not found in time or a rear beam hand is unfair due to the fact that the optical axis is corrected, and finally the imaging quality of a system is influenced.
