Anti-laser eavesdropping electromagnetic shielding two-in-one film

Anti-laser eavesdropping electromagnetic shielding two-in-one film is a high-transparency safety window glass film that attenuates electromagnetic waves and infrared lasers. It utilizes materials that block infrared lasers, and on this basis, materials that attenuate electromagnetic waves can be added. This film product is manufactured through a special optical precision coating composite process and offers excellent light transmission. Therefore, this product integrates the functions of laser eavesdropping blocking film and electromagnetic shielding film, enabling a single film to meet the requirements for preventing the leakage of photoelectric information. It effectively prevents the eavesdropping of voice, audio, and other information.
