Optical filtering devices are most commonly produced by incorporating a layer of woven mesh into a sheet of clear acrylic (Per L-P-391D Type 1 Grade C) and machined to fit your specifications. They can be supplied to you from .060 thick.
Optical filtering devices are used in any application where the viewing port has to be optically clear and also shield against unwanted EMI/RFI interference. The mesh that is incorporated in it can provide the needed attenuation, while the gasket and method of termination can provide the desired electrical bond. Gaskets should inhibit moisture and supply conductivity throughout the window. Wire mesh bonded to (SERIES 400), or Oriented in (SERIES 600) either sponge or solid silicone can supply this termination. Other typical interfaces include Conductive Fabric over Foam (SERIES 577), and Particle Filled Elastomers (SERIES 800).
