EMI/RFI Window Reveals Interior Of Shielded Enclosures

The Optically Clear EMI/RFI Window is a custom die-cut EMI/RFI window that enables users to see components or indicators within a shielded enclosure. This type of window finds use in electronics applications requiring a window to view a display with EMI/RFI shielding requirements in the frequency range of 1 MHz to 1 GHz.These laminated substrates are said to exceed the optical clarity of traditional wire-embedded shielded windows and result in reduced tooling costs. The material used is a multilayer silver oxide-based conductive coating applied to a heat -stabilized, optical-quality polyester film. The substrate has a nominal thickness of 8 mills. Adhesive-backed copper tape provides for conductive edge termination. Other materials include substrates of acrylic, polycarbonate and glass. Various filters, including anti-reflective types, are available. Edge-termination options include conductive gaskets and adhesives.
