Usage examples
  • Valguse sisenemine fotokordistisse võib toimuda kahel erineval režiimil.
  • Sisselülitatud fotokordisteid tuleb kaitsta ümbritseva valguse eest, et vältida nende hävimist üleergastatuse tõttu.

photomultiplier preferred
  • photo multiplier - a vacuum tube which converts light into an electrical signal and contains a photocathode and an electron multiplier
  • image intensifier - a device which amplifies light using a photocathode to convert photons into electrons, which are then accelerated by a high voltage or multiplied by a channel plate on their way to a fluorescent screen. This may be viewed directly, or passed to film or a pick-up device.

photomultiplier preferred
Usage examples
  • In order to check the response of the photocell and the photomultiplier proceed as follows: weigh 0,2000 g of pure potassium chromate for spectrophotometry and dissolve in 0,05 N potassium hydroxide solution in a 1 000 ml graduated flask and make up to the mark.
