Measuring dielectric properties. Researcher adjusting ellipsometric equipment. Ellipsometry is an optical technique that analyses the properties of dielectric materials, such as thin films (layers of material that are less than a millimetre thick). Dielectric materials are non-conducting substances that have unique properties in response to an electric field. Photographed at the National Physical Laboratory, in Teddington, UK.
