H11890 Series Photonic Counting Head PMT Module

The H11890 series is a compact photon counting head consisting of a metal-encapsulated photomultiplier with a high-speed photon counting circuit and a high-voltage power supply unit. The photomultiplier's high-voltage power supply and discriminator level are preset to optimum values, allowing photon counting measurements to be performed simply by connecting to a PC. Photon counting measurement data transfer, counter gating time and other necessary adjustments are controlled via the USB interface using commands from the PC.
