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

Chomerics Europe - a division of Parker Hannifin is able to offer a complete range of shielded and non-shielded glass and plastic windows for use in a wide range of product 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.

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 100 ºC and the high degree of design flexibility they allow.

Chomerics windows offer excellent physical properties combined with outstanding shielding performance & optical clarity. 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.

Chomerics provides expert design and technical support for all materials in its comprehensive range of shielded and non-shielded optical products. An online selection guide is also available to help designers choose the most appropriate material for their application.
