For the highest shielding performance a woven microstructure of mesh is bonded between two layers of glass/plastic (stepped window) or a single layer of mesh foil is fixed onto one side of the window with self-adhesive (single window). This can be done by laminating or edge bonding. The windows can be provided with a silver bus bar, a gasket or be supplied with a frame for easy mounting. Windows can optionally be provided with water seal.
Licht transmission
Opacity of mesh windows is 64,5%. A lack of available light need not be a concern, since an average pair of sunglasses allows less than 9% light to come through.
Applications
LCD displays;
membrane switches,
Touch screens
Defence / Avionics etc.

Conductive coating window
For small areas a transparent polyester foil with a highly conductive coating is commonly used. The foil is available with self adhesive or can be laminated onto glass, acrylic, polycarbonate or any other flat surface. The light transmission is 65-95%, depending on electrical conductivity (20-5 Ohm/sq). For the best chemical and mechanical durability and transparency the transparent conductive coating is sputtered directly onto glass or polycarbonate. However, a mesh foil window provides higher shielding performance than a coated window.
