Shielded windows support EMI compliance
Non-glass windows meanwhile, use either polycarbonate or acrylic material and are selected for their lightweight, impact and shatter resistant characteristics, operating temperature ranges up to 100 ºC and the high degree of design flexibility they allow. Features such as enhanced optical filters, hybrid laminated glass and plastic filters with an integrated metal mesh for EMI shielding, hydrophobic, oliophobic, anti-reflective and anti-fogging coatings can all be included to meet the requirements of specific applications.
The use of large screen sizes as well as the high graphical content of modern equipment applications has made compliance with EMI regulations and ensuring reliable performance an increasingly significant challenge for design engineers. Fitting a shielded window over a display aperture can restore the EMI-blocking property of an otherwise conductive enclosure.
