These films are typically used for applications that demand high visible light transmission and an electrically conductive surface. ECI’s transparent conductive coatings are deposited to customer specified ohms per square and transmission values on glass, semiconductor materials and polymer optical substrates. The resistivity can be varied from 4 to 1,000 ohms per square on glass substrates. For further contrast enhancement and high performance transmission, ECI offers an electrically conductive ITO film with the performance of an anti-reflection design. Designs are available (#949HR) that have high visible transmission and excellent infrared reflection. These films are suitable for applications that need high white light transmission and broad banded IR rejection.
