Standard & Optical EMI Shielding Mesh

EMI shielding mesh is made of stainless steel wire mesh as well as copper and brass woven wire mesh to protect key equipment from RFI (Radio Frequency Interference) and/or EMI (Electromagnetic interference).

We have standard and optical shielding mesh for your specific requirements and the shielding meshes are flexible products which can be supplied in rolls, cut into pieces or as fabricated parts to suit individual requirements.

Several electromagnetic waves.
Benefits for EMI Shielding
  • Effective shielding of electromagnetic radiation
  • Assist avoiding the "Corona Effect" (air around component becoming conductive)
  • High optical transparency
  • Available in stainless steel, copper, brass and other alloy metals.
  • Excellent fire and corrosion resistance
  • Uniform mesh size and wire diameter
  • Flat surface
  • No oil spot.

Optical Shielding Mesh – Blackened Woven Wire Mesh
Optical Shielding Mesh – Blackened Woven Wire Mesh

For high demands on shielding effect and optical transparency in display panels, shielding meshes have been developed which have an absolutely uniform black coloration and high attenuation values.

This optical shielding mesh, also called EMI shielding glass screen, EMI mesh screen adopts blackened woven wire mesh, including blackened stainless steel wire mesh or blackened copper wire mesh to specially for displays, touch screen, windows on panels for supervision in military, mechanical and medical industries.

This blackened woven wire mesh (stainless steel or copper) is used to provide exceptional shielding performance, high transparency (up to 98%) and reduces glare for improved visibility. It is laminated between various substrates (acrylic or glass) or placed on the side not directly accessible (e.g. back side of a monitor screen) in military, mechanical and medical industries.

This optical shielding mesh provides exceptional shielding performance as well as high transparency (up to 98%).

The optical blackened shielding mesh is available in 100, 80, 50 OPI and more specifications are as follows.
