Difference between Photocathode and Photodetector

Photocathode vs. Photodetector

A photocathode is a negatively charged electrode in a light detection device such as a photomultiplier or phototube that is coated with a photosensitive compound. Photosensors or photodetectors are sensors of light or other electromagnetic energy.

Similarities between Photocathode and Photodetector

Photocathode and Photodetector have 8 things in common (in Unionpedia): Dark current (physics), Photodiode, Photoelectric effect, Photomultiplier, Photon, Photosensitivity, Phototube, Spectrophotometry.

Dark current (physics)

In physics and in electronic engineering, dark current is the relatively small electric current that flows through photosensitive devices such as a photomultiplier tube, photodiode, or charge-coupled device even when no photons are entering the device; it consists of the charges generated in the detector when no outside radiation is entering the detector.

Photomultiplier

Photomultiplier tubes (photomultipliers or PMTs for short), members of the class of vacuum tubes, and more specifically vacuum phototubes, are extremely sensitive detectors of light in the ultraviolet, visible, and near-infrared ranges of the electromagnetic spectrum.

Photon

The photon is a type of elementary particle, the quantum of the electromagnetic field including electromagnetic radiation such as light, and the force carrier for the electromagnetic force (even when static via virtual particles).
