Dontech Incorporated Optical Fine Wire (OFW) and Micro EMI-Mesh (MEM100)

Dontech manufactures a wide variety of conductive optical grids, including woven fine-wire stainless steel and copper, as well as printed silver meshes for optical EMI/RFI shielding of electronic displays, instrumentation and enclosures. The conductive optical grids are typically embedded in glass or plastic substrates such as acrylic, polycarbonate or polyester (PET) or triacetate (TAC). The conductive ground plane is then terminated via a perimeter busbar, extended mesh or conductive gasket. Dontech’s grid counts typically range from 50 to 255 openings per inch (opi). Standard unplated wire width/diameter for most mesh counts is 0.0011” and 0.0022” for woven and 0.0005" for etched mesh. Dontech’s OFW and MEM100 meshes combine excellent shielding effectiveness with optical performance, making them ideally suited for electronic displays and optics applications. Typical applications for conductive optical grids include EMI/RFI shielding of electronic displays and enclosures used in: • Military applications – requiring the attenuation of radiated EMI/RFI emissions and susceptibility per MIL-STD-461 and MIL-STD-464 • Rugged computers, tactical radios, sensors and vehicle-mounted displays • Secure communication systems to meet tempest and FCC compliance and for homeland security • Medical displays – MRI rooms, display and observation windows • Aircraft Shielding – display and instrument panels, aircraft windows and doors • Industrial controls, heavy equipment, shipboard electronic systems • Test and measurement equipment – telecommunication, signal analyzers and generators Dontech woven fine wire mesh is available unplated, blackened, or silver plated and conductively blackened. In addition, a variety of product configurations are available for all conductive optical grids, including: • Laminated in optical substrates: glass, polycarbonate, acrylic, ADC, PET • Optical finishes – antiglare, antireflective, chemical/abrasion resistant • Sheets, cut-to-size • Applied to metal frames and gasketed • Applied to touch screens and digitizers
