PHOTON COUNTING UNITS
C3866, C6465
Photon counting units are 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 C3866 uses a high-speed electronic circuit that allows
measurement with an excellent output linearity up to 10
7
s
-1
. The
C3866 also has a prescaler (division by 10) eliminating the need
for a high-speed counter.
The C6465 provides an output linearity up to 10
6
s
-1
and an output
pulse width of 30 ns, making it suitable for use with a general-
purpose counter.
