Metal Package PMT
Photon Counting Head H11890 Series
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 photo-
multiplier tube and the discriminator level are preset to optimum values, al-
lowing 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.
Since the H11890 series performs linearity correction by the internal MPU, it
provides excellent count linearity within a range of -10 % at 2 × 10⁷ s^-1.
