The micro-channel plate fits between the photocathode and screen.
Photocathodes divide into two broad groups; transmission and reflective.
Caesium iodide photocathodes are highly efficient at extreme ultraviolet wavelengths.
These photocathode devices do not detect temperatures, but rather infrared radiation variances.
The S20 photocathode has a sensitivity of around 150 to 200 �A / lm.
The photocathode emits at most one electron for each arriving photon by the photoelectric effect.
Instead, a caesium iodide phosphor is deposited directly on the photocathode of the intensifier tube.
The light is focused onto the photocathode of a photomultiplier tube that triggers an electron avalanche.
Various filters, photocathodes, and electronics aided in collecting data in several ultraviolet light passbands.
The photons which are coming from the light source fall onto the photocathode, thereby generating photoelectrons.
