Cylindrical surface optical window electromagnetic shielding metal mesh film coating clamp

The invention discloses a cylindrical optical window electromagnetic shielding metal mesh coating clamp which comprises a metal film clamp, an electrode clamp and an antireflection film clamp, the metal film clamp, the electrode clamp and the antireflection film clamp all comprise clamp bodies, and rectangular holes used for containing cylindrical optical parts are formed in the clamp bodies. A rectangular hole is formed in the upper end of the clamp body, a supporting edge used for bearing a cylindrical surface part is arranged in the rectangular hole, the included angle between the extension line of the lower end of the clamp body and the upper end of the clamp body is 16 degrees, the clamp can be well matched with a tool disc, the edge cannot be damaged in the film coating process, a diffraction edge film layer cannot fall off, and the film layer is good in quality. 100% coating of the surface of the cylindrical optical part is achieved, the coating precision of the cylindrical optical part is improved, an
