Dontech has introduced the OFW (Optical Fine Wire) and MEM100 (Micro EMI-Mesh) conductive optical grids. They 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 whereas the MEM100 series is made of etched and blackened copper. The optical grids combine shielding effectiveness with optical performance, which makes them suitable for electronic displays and optics applications, including military, which requires the attenuation of radiated EMI/RFI emissions and susceptibility per MIL-STD-461 and MIL-STD-464. Other applications include aircraft, medical and industrial displays, rugged computers, communication systems and test equipment. The grid counts range from 50 to 255 openings per inch. The standard unplated wire width/diameter for most mesh counts is 0.0011 and 0.0022inch for woven and 0.0005inch for etched mesh. The optical grids are embedded in glass or plastic substrates such as acrylic, polycarbonate or polyester or triacetate. The company's woven fine wire mesh is available in unplated, blackened, or silver plated and conductively blackened varieties. Customised product configurations such as substrate, optical finish, sheet format and assembly are also available on request for conductive optical grids.
