Hamamatsu C9744 Photon counting unit Datasheet

PHOTON COUNTING UNIT
C9744
Photon counting unit is designed to convert single
photoelectron pulses from a photomultiplier tube into 5 V
digital signals by use of the built-in amplifier and
discriminator circuits. Photon counting with a high S/N
ratio can be performed by simply connecting a counter to
the output of the photon counting unit.
The C9744 uses a high-speed electronic circuit that
allows measurement with an excellent output linearity up
to 107 s-1. The C9744 also has a prescaler (division by
10) eliminating the need for a high-speed counter.
