Parker Chomerics WIN-SHIELD™ Elite EMI Shielded Window
Categories: Polymer; Thermoplastic; Polycarbonate (PC); Polycarbonate, Optical Grade

Material Notes: Description: Shielded Windows WIN-SHIELD™ Elite EMI shielded windows provide exceptional optical performance without sacrificing EMI shielding. This new generation of shielded windows is designed specifically to address shielding concerns in electronic equipment such as medical devices, industrial process, measurement and control equipment, and test equipment. WIN-SHIELD™ Elite windows use a proprietary mesh shielding design that provides superior light transmission and EMI shielding properties when compared to traditional shielded window designs. Total shielded window light transmittance properties; result from the mesh, substrates and surface finishes used. This new design also minimizes the typical problem with text distortion on display screens caused by the shielding mesh orientation, i.e., the moiré effect. WIN-SHIELD™ Elite EMI shielded windows are manufactured as a fully laminated construction with optically matched adhesives and front and rear UL HB rated, optical grade, polycarbonate substrates
