BQX-BM025 Dual-Purpose Shield

• High Blocking Efficiency: With a light transmittance of 56-70%, the film effectively blocks 99.9% to 99.99% of signals, providing exceptional protection against unwanted surveillance.

• Stable Performance Over Time: Despite potential laser-induced thermal effects or prolonged exposure to high power lasers, which may leave marks on the surface, the film maintains its blocking efficiency without degradation.• Versatile Countermeasures: It counters a variety of eavesdropping techniques including intensity detection, speckle detection, Doppler frequency detection, and Doppler phase detection, offering comprehensive protection against sophisticated spying methods.• Innovative Anti-Laser Eavesdropping Agents: Developed using proprietary technology, the specialized anti-laser eavesdropping material and corresponding manufacturing processes ensure high light transmittance, uniformity, long service life, and superior performance.• This particular anti-laser eavesdropping film maintains its blocking efficiency unaffected, even when subjected to scorch marks as a result of prolonged exposure to high-power laser radiation and the resulting thermal effects. This resilience ensures consistent performance under extreme conditions, providing reliable protection against laser-based espionage attempts despite potential physical damage to the film's surface.
