Technical content

The H7468 series are photosensor modules assembled with a photomultiplier tube, an AD converter circuit and a microcontroller. These photosensor mod- ules operate from a single +5 V supply and convert the photomultiplier tube analog signals into 12-bit digital data which can be sent to a PC (personal computer) through the RS-232C interface. The photomultiplier tube supply voltage and measurement start/stop can also be controlled from the PC.
