QX3 Digital Image Gallery
Capacitor
Capacitors are used to temporarily store electrical charges in electronic and electrical circuits. They are usually composed of one or several metallic plates separated by an insulator. The digital images below reveal plates and insulation in a miniature electronic capacitor that has been dissected.
These images were captured using the oblique illuminator built into the microscope head with the assistance of a Dolan-Jenner Model 180 fiber optics illuminator using a 150 watt projection lamp. The light pipes of the illuminator were placed at approximately a 45-degree angle with respect to the optical axis of the microscope and were positioned to evenly illuminate the specimen. A 2-inch square section of black paper was placed over the diffusion filter on the stage of the microscope to avoid any glare from transmitted illumination.
