Description
Electromagnetic Interference (EMI) can be described as any form of electrical disturbance, signal or noise which interferes with the ability of electrical or electronic equipment to function correctly.
This interference is also referred to as Radio-Frequency Interference (RFI) and is active throughout the environment. Its effects vary from impaired TV or radio reception to severe disruption of communications, data processing and medical and defence activities. Its sources are both natural and man-made.
It is also necessary to contain emitted signals from computer and data handling equipment to prevent electronic eavesdropping for example, where these signals may interfere with other sensitive electronic equipment in the nearby vicinity. The simplest way to achieve this is by the Faraday Cage Principle and in effect, this is what happens in most cases (metal frames or casings placed over the source of the emission).
Our shielded windows are an extension of this principle in that the fine wire mesh acts as a barrier to these emissions but at the same time allowing the operator sight of the display into, or out of the shielded room or area. The windows on their own will not solve RFI problems but must be an integral part of a fully shielded system.
