Get Price2016-11-9 · This light detector is a current-to-voltage converter. The FET input op-amp prevents the loading of the photodiode and the voltage at the output is proportional to the current in the photodiode. So long as the photodiode response to the light is linear, the output voltage is proportional to the light falling on the photodiode.
Get PriceThe light is transformed inside the structure into an electric current.
