Product Features

1. The surface anti-scratch layer effectively withstands daily maintenance and is easier to clean than traditional coatings;

2. The nano-functional composite layer is located in the middle of the multi-layer optical PET film. The inorganic material ensures long-lasting functionality without degradation, eliminating the drawback of reduced protection after scratches in traditional coatings;

3. Wide protection spectrum, effectively blocking diffuse reflection listening lasers of various wavelengths;

4. Provides comprehensive protection against lasers from any incident angle, overcoming the limitation of traditional coatings that only protect against direct incidence;

5. The film materials are all optical-grade and neutral in color, ensuring no color distortion in the field of view.
