Head-on PMT
Photon Counting Head H9319 Series
The H9319 series photon counting heads are designed to perform photon
counting by just connecting to a PC. The H9319 series includes a 25-mm (1")
diameter head-on photomultiplier tube, a photon counting circuit, a high-volt-
age power supply circuit, counter and a microprocessor. Data transfer, meas-
urement time and other necessary adjustments can be controlled by com-
mands from the PC through the RS-232C interface.
Since the H9319 series performs linearity correction by the internal micro-
processor, it provides excellent count linearity within a range of ±1 % at
20 × 10⁶ s^-1.
