The invention discloses an electromagnetic shielding light window of a double-layer interlaced multi-cycle metal ring embedded array and belongs to the technical field of electromagnetic shielding. The electromagnetic shielding light window is formed by arranging two layers of metal grids in a rotating and interlaced mode and loading the two layers of metal grids on the two sides of a light window transparent substrate or a substratum. Each layer of metal grid is formed by densely arranging and connecting a set of concentric metal rings and another metal ring with the different diameter in an equilateral triangle mode, and the metal grids are distributed and loaded on the surface of the light window transparent substrate or the substratum in a crossed mode. The adjacent rings with the same diameter are communicated in an external tangent mode. The concentric rings are aligned with the external rings to serve as basic rings which are internally provided with metal sub rings communicated with the concentric rings in an internal tangent mode. Lines are overlapped at the joints where the rings are communicated in a tangent mode or metal which ensures reliable electric connection between the points of tangency of the metal rings is arranged at the joints where the rings are communicated, and therefore it is ensured that all the rings are mutually conducted. Through selection of interlaced angles of the double layers of grids, the structure of the metal grids of the electromagnetic shielding light window can effectively reduce non-uniformity of high-level diffraction light intensity distribution of the grids, and therefore stray light generated by diffraction can be distributed more evenly, and influences on imaging are less.
