Patented RF-FilterVu Shielded Window with Aluminum Mounting Frame


Mission Darkness RF Shielded Window blocks signals and allows you to view contents and device screens behind it

The patented Mission Darkness™ 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).

Easy Installation

The window is a simple and effective way to offer a viewing portal in shielded enclosures and DIY faraday projects. Ensure that shielding is maintained by mounting the window directly onto a conductive material, such as TitanRF™ Faraday Fabric.

Scientifically Proven Performance, Lab Tested and Certified

Shielded Window Laboratory Testing, to Confirm Shielding Effectiveness Standards IEEE 299-2006

Testing Completed by Keystone Compliance Laboratory on September 24, 2021

The Shielded Window has been tested and certified to meet shielding effectiveness standards IEEE 299-2006. The shielding effectiveness test was conducted by Keystone Compliance, a full-service regulatory compliance laboratory offering solutions for nearly all EMC/EMI, environmental, ISTA-certified package and ingress protection testing requirements. IEEE 299-2006 is the standard test method for measuring the effectiveness of electromagnetic shielding enclosures and materials. A properly-shielded device will effectively retain all RF energy in its faraday enclosure and keep all external RF isolated. The Shielded Window is advertised as a product that can be used to maintain conductivity in isolated rooms/enclosures, by blocking the frequency range most mobile devices and electronics transmit/operate within. To provide validation for this claim, the shielding effectiveness test measured how well the window shields frequencies between 1.5GHz to 40GHz. The positive test results provides authentication of its shielding abilities; contact us for a copy of the full test results. The images below were taken during the shielding test.

Complete Your Project with TitanRF™ Faraday Supplies

Use TitanRF faraday supplies for the construction of your EMI/EMR reduction project or RF shielding enclosure. TitanRF Faraday Fabric can be used to create a shielded room or faraday cage. TitanRF Faraday Tape can be used to connect multiple fabric sheets or panels, seal enclosures, mend punctured fabric, and more.

The fabric and tape are often used to make the shielded window installation easy, efficient, and to maintain conductivity.

Additional RF shielding materials include foam gaskets, patches, and vents. Watch the video to see how all of the materials can be used to build a faraday box.
