C8855-01_15 Datasheet, PDF (4/4 Pages) Hamamatsu Corporation – USB INTERFACE COMPATIBLE COUNTING UNIT

RELATED PRODUCT
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.
