- When light strikes a photocathode inside the tube, an electron is emitted, which accelerates toward the first anode in a multiplier unit.
- Interactive Flash Tutorial Photomultiplier Tubes Discover how photomultipliers work by amplifying the electrons generated by a photocathode exposed to a photon flux.
- Any available light from the outside world enters the lens and strikes a special device called a photocathode.
- The photocathode converts the few photons that strike it into a corresponding pattern of electrical energy called electrons.
- The next evolution of the technology involved a more advanced photocathode that could further improve the amplification of light.Advertisement
- Instead, they allow light from a very dimly lit location to pass into the goggles, which converts that light into an electrical signal using a special surface called a photocathode.
- Electrons from the photocathode are then amplified and projected onto a screen inside the goggles.
