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.
