Tech Note: ITO Coatings
Transparent conductive coatings are very often used in electro-magnetic shielding, electrical heating, and cutting edge display applications. Abrisa Technologies uses the coating material Indium Tin oxide (ITO) which provides for excellent durable coatings.
Index matched ITO provides a combination of low resistivity and extra transmission in the visible spectrum (400-700 nm) with an average transmittance of 94%.
This single layer ITO coating provides an average transmittance of 90% over the visible spectrum (400-700 nm) with resistivity of 120 ohms per square. Standard tolerance for sheet resistivity is ±20%. Higher or lower resistivities are available upon request.
Often, ITO coatings are used in contact with materials other than air. Abrisa Technologies often designs and produces ITO coatings designed specifically to be used next to materials such as liquid crystal, cements, index oils, and various other materials. ITO coatings that have been under coated or over-coated to be index matched to a particular material, such as liquid crystal, can have very low reflectances.
