Charge Coupled Devices

Charge Coupled Devices (CCDs) are silicon-based light detectors, widely used in astronomy for imaging of visible, ultraviolet and infrared radiation. They are also used in commercial digital cameras. The introduction of CCDs for astronomical imaging in the late 1970s, as replacements for the photographic plate, made possible many of the breakthroughs that have shaped modern astronomy.
