>>RFI / EMC Filter Windows

Shielded filter windows are designed for use with electronic displays and give a high level of shielding from both internally and externally generated electromagnetic emissions. These windows can be designed to incorporate any of the filter characteristics described in the “Optical Filters and Fascia Panels” data sheet.

RFI / EMC shielded windows can be manufactured in allyl carbonate, acrylic, polycarbonate or glass.  The shielding element is either a cast in micro – fine mesh (allyl carbonate only), laminated micro – fine mesh or ITO deposition.

Cast Allyl Carbonate Embedded Mesh Windows.
These shielded windows offer the superb screening performance of micro – fine mesh, combined with the outstanding characteristics of allyl carbonate (see “Optical Filters and Fascia Panels” for details on allyl carbonate).

The general properties of cast windows are: 

  • Micro – fine mesh is cast in to a one piece sheet, therefore no delamination problems and higher temperature specification than laminated parts.
  • They can be machined to any desired profile, with or without rebates.
  • Extremely good abrasion, solvent, impact and heat resistance.
  • Light weight.
  • Different meshes available to suit the application and mesh is blackened to reduce reflections.
  • None reflective surfaces can be cast in.
  • Mesh can be set at any desired angle.
  • Silver loaded bus – bar termination.
