PMT module uses USB connection for control & power

Hamamatsu Photonics has extended its range of compact photomultiplier tube modules with the H11890 series of USB powered photon counting modules, providing excellent count linearity with correction performed by an internal processing unit. The H11890 series contain a metal package PMT along with a high-speed photon counting circuit and high-voltage power supply unit.

Photon counting measurement involves connecting the module to a PC via USB, which also provides the necessary power to operate the unit.

The high voltage supply for the photomultiplier tube and the discriminator level are 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.

On offer within the series are three different types covering the UV-VIS-NIR range, using either super or ultra-bialkali photocathodes for increased quantum efficiency in the visible region, or multialkali for extended infrared sensitivity.
