Metal Package PMT with Internal Charge Amp+ADC Type
Photosensor Modules H7468 Series
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.
