EMI Mesh Product Range
1.0 Overview
Visiontek Systems offer a range of 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.
2.0 Product Range
Blackened 100 opi copper is a rugged mesh that is recommended for standalone use
EmiClareMesh is Visiontek Systems proprietary mesh optimised for optical performance without sacrificing EMI performance. EmiClare provides less image distortion (moiré fringing) and higher light transmission than other similar products whilst maintaining excellent EMI shielding effectiveness
EmiClare MicroMesh 2™ offers the combined benefits of a low surface resistance conductive grid and a high transmission moiré optimized design. The double side blackened metal deposition process used in the production of EmiClare Micro Mesh leaves the aperture clear. This allows single side lamination to the rear of touchscreens and cover glass or as a drop-in filter in suitable applications and environments
Conventional plated and blackened stainless steel metal meshes are also available
3.0 Key Features
Range offers several options allowing for custom design to suit the specific requirement
Optimum optical performance & shielding effectiveness
Blackened option to eliminate light reflections. Visiontek Systems proprietary blackening system is highly conductive
4.0 Benefits
Maximum shielding performance with no optical compromise
Mesh blackening is highly conductive therefore enhances shielding effectiveness at frequencies below 10GHz
5.0 Applications
Avionics displays & in-flight entertainment, touch screens, ruggedized displays, GPS, medical and handheld displays
