EMI shielding windows

High EMI shielding performance Optimum optical transparency Wide range of working temperature Ultrathin Logo can be printed

General Description

EMI shielding windows consist of one or more window layers with a conductive intermediate layer. They are applicable for all visual display systems to protect them from electromagnetic interference, e.g. in meters and monitors.

 Due to the variety of possibilities, our EMI shielded windows are custom-made production. The windows should be selected according to following criteria:

Window material, Color of material, Dimensions, AR (anti-reflectivity), Type of intermediate layers, Construction, Gasket type, Frame finish

1. Window material

Optical glass, Plexiglas (PMMA), Makrolon (polycarbonate), PVC

2. Color of material

3. Anti-reflectivity

All materials can be supplied with anti reflective surface to avoid glaring and to enhance contrast.

4. Type of intermediate layers

Copper mesh, stainless steel mesh, conductive foil or ITO film

The mesh can be blackened so as to enhance contrast and plated with various metals to improve the performance. To avoid interferences between mesh grid pattern and monitor or display ("Moiré fringes"), simply change the orientation of the mesh by turning it a little.

5. Construction 

Plain ending (Flying Plain Mesh)                                                           Step construction

 

6. Gasket Type

To achieve shielding effectiveness, a good contract between the mesh and the enclosure is required. The contract can either be established in a direct way or by means of a conductive gasket.

7. Frame Finish

Windows can be supplied from the factory as complete units. The finish is made according to customer specification and facilitates the assembly. The appropriate gasket is integrated in the frame to provide a good contact between mesh and enclosure.

You can also choose the copper foil or silver busbar instead of conductive gasket.
