Photon counting head
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-voltage power supply circuit, counter and a microprocessor. Data transfer, measurement time and other necessary adjustments can be controlled by commands from the PC through the RS-232C interface. Since the H9319 series performs linearity correction by the internal microprocessor, it provides excellent count linearity within a range of +/-1 % at 20 x 106 s-1.
