Shielded windows support EMI compliance in growing number of products with high graphical content.

Chomerics Europe is now able to offer a complete portfolio of shielded and non-shielded glass and plastic windows for use in a range of products in both portable and fixed location equipment.

Typical applications can be found in markets that include military, medical, public information display and test and measurement equipment.

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.

Glass windows offer the best optical clarity and transmission along with good scratch resistance. 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 100ºC and the high degree of design flexibility they allow.

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.
