The Mission Darkness™ Patent Pending Gen 2 RF-FilterVu Shielded Window is primarily used to obtain effective radio frequency shielding while allowing users to see through the transparent window, for uses such as faraday cages, EMI/RF shielded rooms, forensic boxes, EMP protection bins/sheds, or any type of shielded enclosure. It has been lab tested and certified to shielding effectiveness standards IEEE 299-2006. The window is clear enough to distinctly view contents behind it, including mobile device screens. The attached frame is fabricated from a high-performance and corrosion resistant aluminum material, and includes a conductive gasket for mounting it to it a flat surface and maintaining conductivity. There are 24 pre-drilled holes in the frame, allowing the user to install it using whatever attachment method works best for their particular use and materials (*additional installation hardware not included).
