Optical mirror magnetic suspension supporting device

Abstract

The invention discloses an optical mirror magnetic suspension supporting device. The optical mirror magnetic suspension supporting device comprises an axial electromagnetic guiding device, a radial electromagnetic guiding device and an optical mirror fixing device. In the axial electromagnetic guiding device, electromagnets I are uniformly mounted on a bottom plate at the lower end of the opticalmirror fixing device, and permanent magnets I are uniformly mounted at the bottom of the optical mirror fixing device. In the radial electromagnetic guiding device, electromagnets II are uniformly mounted on the inner sides of vertical mounting plates on the edge of an electromagnet mounting frame through screws, and permanent magnets II are uniformly mounted on the outer wall of the optical mirror fixing device through set screws. The side face of an optical mirror to be processed is limited and fixed to the optical mirror fixing device through locking screws. The optical mirror magnetic suspension supporting device can implement height supporting and posture adjustment on the mirror in the optical primary mirror processing process. The supporting device is effectively protected against damage caused by processing impact or vibration through flexible supporting. Meanwhile, the problems of friction, leakage, stagnation and the like occurring through an original supporting method are solved. The optical mirror magnetic suspension supporting device is easy to maintain and convenient to operate.

However, in the processing of large aperture and optical mirror, the difficulty of supporting the primary mirror also increases

At present, cylinder support and hydraulic support are mostly used as the main support methods in the support process of the optical primary mirror. There is a problem of cylinder oil leakage in the support process of the hydraulic cylinder support system, which will affect the use in the dust-free and pollution-free laboratory environment. It has an irreversible impact on the processing of large optical mirrors; the cylinder support method has poor stability and high repair rate, resulting in increased costs and reduced processing efficiency; and the above two support methods are inevitable in the vertical direction when adjusting the mirror surface. The energy loss caused by friction will affect the adjustment accuracy of the support force, thereby affecting the mirror processing accuracy
