All intrusion lasers are cut off and cannot be detected;

Due to the thermal effect of the laser, there will be “bullet marks” permanently retained under high-power detection, and the blocking efficiency remains unchanged;

High light transmittance, does not affect normal lighting;

It is consistent with the appearance of ordinary window film, and cannot be distinguished by the naked eye without professional inspection.

Laser wiretapping blocking ability: >99.99% Infrared blocking ability: ＞99.9% Transmittance: ＞58%

Eavesdropping detection: “Laser bullet marks” function Warranty: indoor installation, warranty for 5 years Appearance: the appearance is the same as ordinary film.

Laser wiretapping blocking ability: >99.9% Infrared blocking ability: ＞99.5% Transmittance: ＞62%

Electron microscope photo of laser wiretapping blocking film

The following figure is a high-definition photo of the blocking film taken with a professional electron microscope. Under a very large magnification, you can clearly see the distribution of the core “laser wiretapping blocking agent” of the laser wiretapping blocking film. It can be clearly seen from the figure below that the distribution of the product’s blocking agent is very uniform, which also means that the product has reached the best performance and has the best effect of high transparency, high definition and high blocking.
