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.
