Description
Photon counting head
The H11890 series is a compact photon counting head consisting of a metal package photomultiplier tube along with a high-speed photon counting circuit and a high-voltage power supply unit. The high voltage supply for the photomultiplier tube and the discriminator level is preset to optimum values, allowing photon counting measurement by just connecting to a PC. Photon counting measurement data transfer, counter gate time, and other necessary adjustments are controlled by commands from the PC through the USB interface.
