▎ 摘　　要

NOVELTY - An electromagnetic shielding optical window comprises a transparent absorption layer (3) that are sequentially overlapped and arranged in parallel with a transparent medium A (4), a metal net grid A (5), a transparent medium B (6) and a metal net grid B (7). The transparent absorption layer comprises six layers of graphene films separated by transparent medium of metal mesh grid A and metal mesh grid B that are in parallel to form a translucent reflective layer. USE - Electromagnetic shielding optical window. ADVANTAGE - The electromagnetic shielding optical window has high light transmission, high electromagnetic shielding characteristics, and low electromagnetic reflection. DESCRIPTION OF DRAWING(S) - The drawing is a schematic diagram of the electromagnetic shielding optical window.
