Name: Functional film (laser wiretap blocking film)
Visible light transmittance: 60±2%
Laser blocking band: 780nm-2500nm
Width: 1.52m
Function: Absorb infrared laser to protect privacy.
Optical density
1) The comprehensive blocking rate of the infrared band (850nm~1000nm) is over 99.95%%%, and the OD value>2
2) The comprehensive blocking rate of the infrared band (1000nm~1400nm) is over 99.95%%%, and the OD value is >3
3) The comprehensive blocking rate of infrared band (1400nm~1800nm) is above 99.99%%%, and the OD value>4
Features:
1. The appearance of the film is no different from that of the ordinary film, which can not be distinguished by the naked eye and is more concealed
2. Good light transmittance, low haze, does not affect sight and lighting
3. The measured signal-to-noise ratio is -35db~-40db, and the result is noisy or silent
4. Broadband protection (780-2500nm +0-400nm) to prevent technology update and iteration
5. Product diversity (custom-made anti-laser PVB glass, PET, anti-laser nano-coating)
