| Photomultipliers convert a light stimulus into an electrical signal. In order to accomplish this, the photomultiplier performs two functions. Firstly, it converts input photons into photoelectrons -this is the purpose of the photocathode. The magnitude of the photo-current is too low for conventional electronics to handle, and so amplification of the signal, typically by a factor of 104 to 108, is required depending upon the light levels involved; this is the second function of the photomultiplier. | ||||||||||||||||||||
