| CLEARSHIELD Filters are custom designed flat or curved RFI Shielded Optical Filters produced by depositing a thin electrically conductive transparent coating directly onto the substrate material. The transparent conductive coating provides high shielding performance coupled with good light transmission properties. Laminated CLEARSHIELD Filters are available with a wide range of surface finishes including etches, anti-reflection and non-glare coatings and can incorporate polarizers, for contrast enhancement and coloured filters to match optical requirements. Advantages of CLEARSHIELD Optical Filters: ٕ High conductivity coatings resulting in attenuation of 18to 35dB over the freguency range IMHzto 1GHz Light transmission, typically 87% for 3mm thick coated glass Օ Available as fully laminated flat or curved Window materials consist of glass and polycarbonate substrates | ||||||||||||||||||||||||||||||||||||||
| EMI Shielding Performance The Shielding Effectiveness of CLEARSHIELD filters has been measured by independent test methods consistent with MIL-STD-285. Typical Shielding Effectiveness is shown in the table. | Spectral Performance Optical transmission, averaged over the visible range of 400 to 700nm at 0° angle of incidence are shown in the table. | |||||||||||||||||||||||||||||||||||||
