What is mesh foil?
Mesh foil is a very fine wire mesh laminated between two layers of transparent foil. The wires are so fine that you can hardly see them. The foil is very strong but it still bends very easily.
The mesh, fully integrated in the foil, is protected by a scratch resistant layer so it is easy to apply onto glass, acrylic and polycarbonate, by hand or with a laminator. Depending on the mesh quality it covers anything between 10 kHz and 30 GHz. The finer the mesh, the more effective it is for reducing high frequencies. The foil can be delivered with flying mesh on the sides or around the foil. It means that a piece of the very fine wire mesh will not be laminated with transparent foil. The uncovered piece of wire mesh can be used to make an electrical connection with your enclosure.
Alternatively a conductive or non-conductive adhesive can be provided along the edges or there can be a silver bush bar around the circumference.
A seal with a water/EMI gasket is another option. They mesh foil can be processed in various forms available:
- stainless steel
- blackened copper
- phosphor bronze.

Mesh foil applications
- shielding displays
- shielding windows
- shielding touch screens
- shielding monitor and LCD screens
- tempest shielding
|
|
Type of window options
- Mesh placed under a custom angle to prevent moiré effect
on your display. (Standard is 0 degrees).
- Only sheetstyle 1 and 5 are available
- Mesh foil laminated on your window, or on a new window made
of polycarbonate, acryl or glass. In this option it is also possible
to laminate the mesh under a custom angle.
- Mesh foil with or without transparent self adhesive used to
stick on any normal window or display.

Higher optical grade
When you want a higher optical grade you can add 'HOG' (Higher optical grade) behind the partnumber. Then the products will be selected on even the smallest optical defects such as dust particles. The price for a HOG product is higher than for the usual product.
