▎ 摘 要
NOVELTY - The electro-optical window has a substrate material (11) that is transparent to at least one of near-infrared (NIR), mid-wave infrared (MWIR) and long-wave infrared (LWIR) radiation. An electrically conductive continuous thin film coating (12) is applied on the substrate material, and made of graphene. A multi layered AR coating (13) protects the film coating against environmental conditions. USE - EMI shielding electro-optical window for electro-optical system used for surveillance. ADVANTAGE - Transmittance of light with wavelength in NIR and MWIR spectrum is enhanced, while suppressing EM radiation between 100 mega Hertz to 20 giga Hertz range. High resistance to environmental damage is ensured since the multi layered AR coating protects the film coating against environmental conditions. DESCRIPTION OF DRAWING(S) - The drawing shows the cross sectional view of the EMI shielding AR coated lens.
