EMI Shielded Polycarbonate Windows

Defined polycarbonate laminates can be machined, busbarred and gasketed to your requirements within a short lead-time without compromise of quality or performance. The materials and manufacturing techniques have been optimized for optical and EMI performance and cost. Panels are manufactured and processed in a quality environment.

Hard coatings are applied via a gravure printing process in a class 1000 clean room environment. This process avoids coating irregularities and stressing of the polycarbonate associated with solvent-based spray coating.

Non-Glare coating is a variation of the hard coating with a gloss level of 55 units at 60°. The coating has total uniformity and avoids the localized changes in density associated with spray coating systems.

In additional to the rapid service polycarbonate range, shielded windows can be custom designed in glass, polycarbonate or acrylic with a variety of display enhancement features. Examples of this are:

Offered in large glass lamination, these windows are supplied with a mesh extension over a neoprene gasket. This allows the window to form a compression contact to the metal window frame or to be bonded directly to the shielding of the wall. A single window provides shielding of 80dB at 32.5 MHz, and a double-glazed arrangement with two windows provides in excess of 100dB.

Using a proven design for laminated transparent heated windows based on a high transmission, low reflectance ITO coating on a glass substrate, these laminates can also include other features such as EMI shielding, AR coatings and privacy filters. The recommended power supply is 24vdc and 1-2 amps. The windows are usually laminated with the ITO heater surface to the inside to protect the coating and ensure even heat distribution.

A range of high definition windows for test and measurement instruments can be made in glass or plastic with a variety of surface treatments including silk-screen printing. The shielding elements are optimized for EMI attenuation and optical performance.

Multifunctional windows that deal with sunlight readability, viewing angles, EMU, impact resistance, environmental and mechanical conditions consistent with military and commercial aircraft applications are available in a variety of substrates and even complex shapes.

Ruggeredized touch screens with glass or polycarbonate that can incorporate circular polarizers for contrast enhancement, privacy filters for control of viewing angle, metal mesh or ITO contains for EMI and transparent heaters for defogging and/or heating of the flat panel display.

Windows to enhance the performance of displays in the wide variety of ambient conditions encountered. Properties that can be included are impact resistance, sunlight readability and EMI shielding.
