Metal package PMT
Photosensor Modules H5784 Series
The H5784 series photosensor modules are comprised of a metal package pho-
tomultiplier tube, a low-power consumption high-voltage power supply and a low
noise amplifier. The electrical current from the photomultiplier tube is converted to
a voltage by an amplifier for easy signal processing. The H5784 is highly resistant
to noise since the amplifier is installed near the anode output pin of the photomul-
tiplier tube. The amplifier feedback resistance of 1 MΩ allows a current-to-voltage
conversion factor of 1 V/µA, and covers a frequency bandwidth from DC to 20
kHz.
