EMI Mesh Comparison Data Sheet
Woven meshes for shielded windows, apertures and displays where an electronic enclosure requires shielding from electromagnetic interference (EMI) or is emitting electromagnetic energy which may cause interference with another system but requires a high level of visible light transmission or image clarity.
Blackened 100opi copper is a rugged mesh that is recommend for standalone use.
EmiClare is Optical filters proprietary mesh optimised for optical performance without sacrificing
EMI performance. This is only supplied in finished window formats.
MicroMesh is an etched copper grid matrix with higher light transmission and optical clarity. This is only supplied in fully laminated windows.
Conventional stainless steel metal mesh and coated woven fabric are also available.
Low ohms/sq EMI-ITO coated film that has no grid pattern.
To eliminate light reflections the mesh is blackened. Visiontek Systems proprietary blackening
system is highly conductive and enhances shielding effectiveness at frequencies below 10GHz. The stainless steel meshes are copper plated before blackening.
Window design options
Refer to EmiClare data sheets for finished window options.
Custom optical laminations in glass, polycarbonate and acrylic.
Cut to final size or complex form by CNC with optional conductive tapes or gaskets.
