RFI Mesh Optical Filters

The ZYSHIELD range of RFI niters are designed to give the highest levels of RFI/EMI shielding combined with excellent optical performance.

Display quality micro-fine mesh, incorporating a glare reducing proprietary coating is laminated or bonded to glass, acrylic or polycarbonate to offer the most effective and unique solution to shielded display problems.

The above results are based upon 300mm x 300mm mesh samples tested by independent test houses under laboratory conditions, consistent with MIL-STD-285 and are for guidance only

The transmission values are theoretical calculations based upon mesh only, amendments to the transmission must be made in accordance with the optical characteristics of the carrier or substrate medium.
