EMI Shielding Windows

Electronic displays and enclosures used in military, avionics, medical, industrial and telecommunications, are normally required to meet the electromagnetic compatibility (EMC) standard, which provides protection against interference. Shielding windows have characteristics of both shielding effectiveness and light transmission. As unique optical shielding materials, they are generally applied in viewing areas of electronic equipment.

Bodun provides a wide range of custom-made electromagnetic shielding products with high shielding performance and good optical clarity. For various application requirements, windows can be flexibly designed and manufactured with one or more layers, different substrates, shielding materials, termination methods and other specifications. For displays working under cold environment, a heated glass can be integrated into the window for defogging and defrosting needs. We also provide a series of ultrathin shielding products for situations with strict limit on thickness.
