DONTECH OPTICAL FINE WIRE (OFW) AND MICRO EMI-MESH (MEM100) FOR EMI/RFI SHIELDING OF DISPLAYS AND ENCLOSURES

Dontech’s Optical Fine Wire (OFW) and Micro EMI-Mesh (MEM100) conductive optical grids provide optical EMI/RFI shielding of electronic displays, instrumentation and enclosures. The OFW mesh is constructed of woven and conductively plated fine-wire stainless steel and copper; the MEM100 series is made of etched and blackened copper.

The OFW and MEM100 conductive optical grids combine excellent shielding effectiveness with optical performance, making them particularly well-suited for electronic displays and optics applications, including: military (requiring the attenuation of radiated EMI/RFI emissions and susceptibility per MIL-STD-461 and MIL-STD-464); aircraft, medical and industrial displays; and rugged computers, communication systems and test equipment.

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. The OFW and MEM100 conductive optical grids are typically embedded in glass or plastic substrates such as acrylic, polycarbonate or polyester (PET) or triacetate (TAC).

Dontech woven fine wire mesh is available unplated, blackened, or silver plated and conductively blackened. In addition, a variety of custom product configurations (e.g., substrate, optical finish, sheet format, full assembly) are available for all conductive optical grids.
