Anti-Laser Eavesdropping Blocking Film

The light transmittance of the blocking membrane is 56-70%, and the blocking ability is 99.9%~99.99%.

All intruding lasers are truncated and cannot be detected;

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