The «armored windows» or «armored windows» for Cem screens combine optical transparency and high performance electromagnetic shielding protection. This technology protects equipment sensitive to BF & HF radiated disturbances. AB2E VITCEM consists of thin metal canvases (very fine knits) based on stainless steel or copper, inserted between two transparent optical substrates. The substrates used are usually polycarbonate. The remaining acrylic a fragile material in our field of application Cem or glass for uses in hardened or aggressive medium. Cem seals are in most cases necessary to perform a perfect shielding recovery. Transparent ITO (Indium Tin Oxide) coatings can also be applied to a single substrate. This other technoa of less good performance but a more affordable price. The available dimensions range from a few cm² for smaller sizes, to the sizes of our residential windows.
