Light micrograph of a section through a capacitor with plastic film dielectric. One copper mounting wire (centre) is connected to the thin metal layers with the dielectric films between the metal layers showing blue fluorescence. A commercially available capacitor was embedded in light curing resin and then ground and diamond polished vertically to the mounting wires. Microscopic contrast technique: Incident brightfield combined with UV excitation fluorescence. Magnification 40x when printed 10 centimetres wide. | |
