Anti-Eavesdropping + Electromagnetic Shielding Film

Anti-Eavesdropping + Electromagnetic Shielding Film

Dual-Protection Nano Optical Film

The Anti-Eavesdropping + Electromagnetic Shielding Film integrates two advanced protection technologies — laser signal blocking and electromagnetic shielding — into one high-performance solution. Designed for modern secure environments, it effectively prevents laser-based eavesdropping and electromagnetic interference (EMI) while maintaining high optical clarity.

Key Features

High Definition & Light Transmittance: Maintains clear, transparent visuals without affecting display brightness or visibility.

Ultra-high Absorption & Blocking Efficiency: Utilizes nano absorbing materials to achieve over 99.9% blocking efficiency against eavesdropping lasers.

Broad Shielding Wavelength Range: Effectively blocks infrared and laser signals within 780–2500 nm and shields electromagnetic waves to prevent data leakage.

Full-angle Blocking: Provides complete protection from 0° to 90°, ensuring no blind spots.

Weather, Wear, and Corrosion Resistance: Durable under high/low temperatures, resistant to acid and alkali corrosion — suitable for long-term, harsh environments.

Easy Installation & Maintenance-free: Simple to apply, requires no special tools or maintenance.

Perfect for conference rooms, control centers, laboratories, data centers, and other high-security or confidential spaces, this dual-function film ensures comprehensive protection for both optical and electromagnetic privacy.
