Optical Wire and Grids

August 1, 2010

Dontech (Doylestown, PA) offers optical fine wire (OFW) and micro EMI-mesh (MEM100) conductive optical grids that provide 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 optical grids are suitable for use in military and aircraft applications, medical and industrial displays, rugged computers, communication systems, and test equipment. 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 grids are typically embedded in glass or plastic substrates such as acrylic, polycarbonate, polyester (PET), or triacetate (TAC).
