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 other

optical or mechanical characteristics if required.

Why Select Cast ADC RFI Windows Over Other Designs?

 

 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.

  This production technique creates windows with the best RFI performance and quality combined.

 The general properties of cast windows are ;

 

  • Micro - fine mesh is cast in to a one part construction, therefore there are no delamination problems and they offer a higher temperature                                               specification than laminated parts.

 

  • Cast windows produce the highest possible RFI shielding performance levels of all construction techniques.

  • They can be machined to any desired profile, with or without rebates and holes.

 

  • Extremely good abrasion, solvent, impact and heat resistance.

 

  • Light weight.

 

  • Different meshes are available to suit the application and the mesh is blackened to reduce reflections.

                     

  • Non-reflective surfaces can be cast in.

 

  • Mesh can be set at any desired angle.

 

  •  Silver loaded bus - bar termination.

 

   

 

 

 

   

 

 

 

 

 

 

 

    Laminated Mesh Windows

 

These shielded windows again offer the superb screening performance of micro - fine mesh, which in this version can be left flying for direct termination to the   equipment screen. Material and characteristics for the  filter can be selected from a wide range of available substrates.                                                                                                                                                                                  

         The general properties of laminated windows are ;

  • Micro - fine mesh is laminated in between your selected filter medium.

 

  • Plastic versions can be machined to any desired profile, and glass versions can be constructed with or without rebates.

 

  • This method can be used to produce severe impact resistant windows and fire retardant windows.

 

  • Different meshes available to suit the application and mesh is blackened to reduce reflections.

 

  • Non-reflective surfaces can be included.

 

  • Mesh can be set at any desired angle.

 

  • Various termination methods are available including ; tape edge, mesh over gasket, flying mesh.
