Conductive transparent foil

For smaller areas a transparent polyester foil with ITO coating is commonly used. Applications: LCD displays, membrane switches, etc. The foil has a resistance of 5 Ohm/sq. The coating can be applied on foil, galss and polycarbonate.

Windows with shielding mesh

A woven microstructure mesh is bonded between two layers of glass or plastic. This can be done by laminating or edge-bonding. The windows can be provided with a gasket or be supplied with a frame for easy mounting.

Windows with sputtered ITO coating
Light transmission is 65-95%, depending on electrical conductivity. These windows can come equipped with frame and required EMC gaskets.

10 design tips for windows / displays and transparent foils

1. Do not be afraid of low light transmission coefficients. An average pair of sunglasses has less than 9 % light transmission and you can still see very well through them.
2. In general, a mesh provides higher shielding performance than an ITO coating.
3. Keep the window as small as possible; rectangular windows are better than square windows because the distance from the centre of the window to the edge is smaller.
4. Please inform us of the size in mm that you need and specify the free viewing area.
5. It is cheaper to produce small windows so please specify quantities and sizes rather than square meters.
6. For small windows or little displays you can use foils. It is best to integrate a foil in a display or to mount it onto the edges with copper tape 3201.
7. We can provide windows with a water seal. Please indicate if you want the seal to be on the inside or outside of the window. It is also possible to have a separate water seal on the other side.
8. If an anti-glare or optical coating is needed, please indicate on the drawing from which direction the user will look at it.
9. Only use an anti-glare layer when the object is close to the window, like a monitor. For viewing windows it is better to use an optical coating.
10. To prevent moiré-effects with mesh windows you can indicate the angle of the mesh. When you order a window you can ask us for a sample window and then measure the best angle yourself.
