Specifications
The H7155 series are compact photon counting head devices consisting of a
metal package photomultiplier tube along with a high-speed photon counting
circuit and a high-voltage power supply circuit. The high voltage supply for
photomultiplier tube and the discriminator level are preset to optimum values,
allowing photon counting measurement by just connecting a +5 V supply.
The H7155-20 has an internal prescaler of division by 4. This prescaler im-
proves the count linearity 4-fold compared to the H7155.
